using subsitution method y=x y=-x + 2

Question

Solving systems of equations by substitution method

Answer 1

 

Using subsitution method y=x and y=-x + 2.

y = x
y = -x + 2

Well both are solved for y already so you can substitute the 2nd equation into the first or vice versa.

-x + 2 = x

2x = 2 Subtract x from both sides(I rewrote it in this orientation).

x = 1

If x = 1

y = 1
