Make each equation equal to each other, then solve for x.
-x+2=4x+7
-x-4x=7-2
-5x=5
X=-1
Sub x into one if the y formulas to find y
Y=4x+7
Y=4(-1)+7
Y=-4+7
Y=3
See my picture for how to graph the points.
Hope this helps!
3+x=7Becayse you get the three and add it to a variable equals 7

Answer:
y=50
x=30
z=100
Step-by-step explanation:
x+20=y
2y=z
x+y+z=180
x+y+2y=180
3y+x=180
-y+x=-20
4y=200
y=50
x=30
z=100
