# Word problems regarding a linear equation

If you earned an average of 25,000 over your working life and you retire after 2005 at age 62,63,or 64 , then your annual social security benefit will be \$7000, \$7500, or \$8000. There is a linear equation that gives the annual benefit b in terms of age a for these three years, find the equations

### As a oldage pensioner, can I still earn some money,if so how much/

Are you in the U.S.? Are you talking about Social Security? If so, when you have reached full retirement age, you can earn any amount without penalty. If you are younger than full retirement age, there will be a calculation to show the limit. If you are not in the U.S. disregard this.

### How mutch are we aloud to eaarn on a aged pensioen

The Internal Revenue Service says you can figure out whether you have to pay taxes on Social Security by adding half of your annual benefit to your other income. If the total is more than \$32,000 and you file a joint return, some of your benefits must be reported as taxable income on your tax return. For single filers the threshold is \$25,000. For example, if you file as single and your annual benefit is \$15,000, half of your benefit amount is \$7,500. You you can earn up to \$17,500 in additional income before you hit the \$25,000 mark and have to pay taxes on Social Security benefits.

Hi there,

You cannot solve linear equations on a SHARP EL531. If you would like a calculator that solves equations, you need to get a SHARP EL W506

### Edit Casio FX - 9860G SD have complex equations??

Thhe Casio FX-9860G SD can solve a polynomial equation of degree 2 or 3 with REAL coefficients. If the complex MODE is set to REAL it will find the real roots. If the complex mode is set to a+ib, it will find the real and complex roots.

Apparently it will take coefficients that are real, and will give a Ma Error if any coefficient is complex.

The calculator CANNOT solve equations with complex coefficient. YOU can however convert the system of linear equations with ccomplex coefficients ( of the type you show) as a system of 4 linear equations in 4 unknowns; Split x into a real and an imaginary part, split y into a real and an imaginary part. Substitute Real(x)+iIm(x) for variable x in the equations; substitute Real(y)+iIm(y) for y in the two equations; do the algebra. In each of the original equations split the Real and imaginary parts. You should be able to derive 4 linear equations in unknowns Real(x), Im(x), Real(y), and Im(y).
Use the linear equation solver to obtain the solutions. Recompose x=Real(x)+iIm(x), and y=Real(y)+iIm(y)

Alternatively, after you create the system of 4 linear equations you can use the matrix utility to find Real(x), Im(x), Real(y) and Im(y) and recompose the x and y.

### How can I solve linear and non-linear equations

Set Computational mode to EQN by pressing [MODE][5:EQN]

Select the type of equations you want to solve

Select the relevant otion and get ready to type in the coefficients (the a's, the b's, the c's etc`.)

For more general non-linear equations, use the SOLVE feature.

### Solving simultaneous equation with scientific

Hello,

Let us assume you have two simultaneous linear equations :

a_1*x+ b_1*y+c_1=0
a_2*x +b_2*y+c_2=0

where a_1, a_2, b_1, b_2, c_1,c_2 are coefficients (numerical or algebraic).
The problem is to obtain the particular values of the unknowns x and y for which the two equations are both satisfied: If you substitute the particular values of x and y you find in any of the two equations you discover that both equalities are true.

A small system of equations like the one above can be solved by some very simple algorithms (elimination, substitution, combination) which can be carried out by hand.

The solution of large systems of linear equations can be sought by making use of the concepts of matrices (plural of matrix), determinants, and certain rules called Cramer's rules.

Due to its repetitive nature, the algorithm ( a well defined, limited sequence of steps) is suitable for a calculating machine (computer or calculator).

Certain calculators have, embedded in their ROM, a program that solves linear systems of simultaneous equations. Usually you are asked to enter the values of the coefficients a_1, etc. in a set order, then you press ENTER or EXE (Casio) . If a solution exits (not all linear systems have solutions) the calculator displays it.
