Can someone help me PLZ! I keep posting the same question and no ones helping me : Find the solution to the system of equations below. Start by adding the equations. Write your answer as an ordered pair.

-2x + 2y = -8
2x + y = 5

-2x + 2y = -8     is x=y+4

2x + y = 5          is x= −1/ 2 y+ 5/ 2

Step-by-step explanation:

3x+2y=-3

Step-by-step explanation:

Slope = -3.000/2.000 = -1.500

x-intercept = -3/3 = -1

y-intercept = -3/2 = -1.50000

2x-3y=-15

Slope = 1.333/2.000 = 0.667

x-intercept = -15/2 = -7.50000

y-intercept = 15/3 = 5

If this was helpful then please mark brainliest. Have a great day!

OTHER PROBLEM

y=2x-2

Slope = 4.000/2.000 = 2.000

x-intercept = 2/2 = 1

y-intercept = -2/1 = -2.00000

y=3x-7

Slope = 6.000/2.000 = 3.000

x-intercept = 7/3 = 2.33333

y-intercept = -7/1 = -7.00000

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
