Answer:
Step-by-step explanation:
lets rewrite the equations so that the x and y are on one side and the constant on the other.
2y-x=3
-y+x=0
(we can cancel out the x because one is positive and one is negative)
y=3
(now plug the y value into any equation you want to)
-(3)+x=0
x=3
so our values are
x=3,y=3
