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.

You do not need any graphing calculator to solve this inequality: You have ONE variable.

Simplify your expression

2k-7+1< 7, becomes 2k<13

**k<(13/2) **

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.

this will be the driver also for windows 7 for our lovely webcam ;)

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?

(4+x)(5-x)=(2+x)(7-x)

20-4x+5x-x^2=14-2x+7x-x^2

20+x=14+5x

20-14=4x

x=3/2:ans;

20-4x+5x-x^2=14-2x+7x-x^2

20+x=14+5x

20-14=4x

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

Just plug in one side of the equation and find the answer. Then plug in the other side and compare answers.
