2x + 2y = 6

Choices:
(-4, 1)
(2, -1)

(5, -2)

Answer 1

Are you asked to use a specific method?

Answer 2

x+3y= -1
can u solve for x @love12609784

Answer 3

no it doesnt ask me to use a specific method..

Answer 4

Then this is what I would do.
1) divide the second equation by 2
2) subtract the new second eq from the original first eq

Answer 5

The x's will cancel and you can solve for y.
Then plug in y into one of the original equations to find x.

Answer 6

Of course, you can also follow @Godlovesme 's suggestion above and solve the first equation for x, and use substitution.
