What is the answer to

2y = x + 3

x = y?

This is system of equations: Substitution method.

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
