What is y=1/2x + 2 y = - x + 5 using subsitution

Y=1/2x+2

y=-x+5

subsitute since they both equal y

1/2x+2=y=-x+5

1/2x+2=-x+5

subtract 2 from both sides

1/2x=-x+3

multiply both sides by 2

x=-2x+6

add 2x to both sides

3x=6

divide both sides by 3

x=2

subsitue

y=-x=5

y=-2+5

y=3

x=2 and y=3

solution in (x, y) form is (2,3)
