The answer is c it was - 6+2y

Carina Pena · Answer 2

-x + 2y = 6

6y = x + 18

Let's rewrite these equations.

-x + 2y = 6

6y - x = 18

If we multiply the second equation by - 1 we can add both of them.

-x + 2y = 6

-6y + x = - 18

Add:

-x + (-6y) + 2y + x = 6 + (-18)

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

-4y = - 12

y = - 12/-4

y = 3

Substitute y in the equation:

-x + 2y = 6

-x + 2.3 = 6

-x + 6 = 6

-x = 6 - 6

-x = 0

x = 0
