What is the x-coordinate of the soultion y=x+2 y=-x+6

x+2 = - x+6

2x+2 = 6

2x = 4

x = 2

Both equal y to set equal to each other

x+2=y=-x+6

x+2=-x+6

add x both sides

x+x+2=x-x+6

2x+2=0+6

2x+2=6

minus 2 both sides

2x+2-2=6-2

2x+0=4

2x=4

divide both sides by 2

x=2

the x coordinate is 2
