Answer: (3,4)
multiply both sides of the top equation by 2
get rid of the x variable by subtracting add all corresponding numbers and variables (4+(-4), -4+7, -4+16) which leaves you with 3y=12
divide both sides by 3 which cancels out the 3y and leaves you with y=4
input y in your top equation to find x. (-2x+2x4=2)
this leaves you with x=3
