Question

6x + 2y = 18 -4x - 2y = -6

Answer 1

Answer:

x=6, y = -9

Step-by-step explanation:

6x + 2y = 18

-4x - 2y = -6

Add the two equations together to eliminate y

6x + 2y = 18

-4x - 2y = -6

------------------------

2x +0y = 12

Divide by 2

2x/2 = 12/2

x = 6

Then find y

6x+2y = 18

6*6 +2y = 18

36+2y = 18

Subtract  36 from each side

36+2y-36 = 18-6

2y = -18

Divide by 2

2y/2 = -18/2

y = -9

Answer 2

X=6 y=9
Because you need to place both equation over each other and choose to solve for x or y
