2x+2y=-2
3x-2y=12

I do not understand this math and need help with this math equation.

Step-by-step explanation:

You have two equations and two "unknowns" x and y.

This is an easy one. Add the two equations together, which will eliminate the y terms so you can solve for x:

2x+2y = -2

3x-2y = 12

5x  = 10,   so x = 2.

Now plug the 2 back into one of the equations and solve it for y.

2(2)+2y = -2

4+2y = -2

2y = -6

y = -3

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
