There are no solutions.

x = 1/x
multiply both sides by x: x^2 = 1
take the square root of both sides x = sqrt(1)
this gives x = 1 or x = -1
similarly, y = 1 or y = -1

12x = 12 or 12x = -12
12y = 12 or 12y = -12

subtracting 12y from 12x can only give 24, 0, or -24, never 7.

(5 * 5) -2 +11 + 20+7+5*2=


Simplifying
(5 * 5) + -2 + 11 + 20 + 7 + 5 * 2 = 0

Multiply 5 * 5
(25) + -2 + 11 + 20 + 7 + 5 * 2 = 0
25 + -2 + 11 + 20 + 7 + 5 * 2 = 0

Multiply 5 * 2
25 + -2 + 11 + 20 + 7 + 10 = 0

Combine like terms: 25 + -2 = 23
23 + 11 + 20 + 7 + 10 = 0

Combine like terms: 23 + 11 = 34
34 + 20 + 7 + 10 = 0

Combine like terms: 34 + 20 = 54
54 + 7 + 10 = 0

Combine like terms: 54 + 7 = 61
61 + 10 = 0

Combine like terms: 61 + 10 = 71
71 = 0

Solving
71 = 0

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Give an example of a linear equation, solve it, and then check your work. Explain step-by-step what procedures you used and upon arriving at a solution, carefully check to see that your solution is correct...


4x+7=11 Solve for "x".
subtract 7 from each side of the equation
4x +7(-7)=11(-7) = 4x=4
divide both sides of the equation by 4
4x/4=4/4
therefore
x=1
Correct?

Solving systems of equations by elimination


Hi joanmae jmeh;

You can add these equations just like you would numbers

3x + 2y = 7
5x - 2y = 1
-----------------------
8x =8
x=1
Now plug x = 1 back into either equation and you can solve for y
Y = 2

When you add the 2 equations together the +2y and the -2y cancel
out

Hope this helps Loringh Please leave a rating for me Thks
