Answer 2

@Angel_Bear19 that would work..but what would you do if you didnt have answer choices?

Answer 3

You would have to subtract y from both sides and figure out the value of x then substitute x in the problem to figure out y

Answer 4

1.multiply top equation by 3
2.add the equations canceling the y's
3.solve for x
4.sub x value into any equation to get y

Answer 5

after you get the equation, solve for y, and plug it back to the equation to get for x

Answer 6
