Solve for x for x: x+2y=2
x+2y +-2y=2+-2y (add -2y on both sides.)
x=-2y+2
Substitute : -2y+2 for x in
4x-y=4:
4(-2y+2)-y=4
-9y+8=4 Simplify both sides of the equation.
-9y+8+-8=4+-8 Add -8 to both sides.
-9y=-4
-9/-9=-4-9 Divide both sides by -9
y=4/9
Substitute 4/9 for y in
x=-2y+2
x=-2(4/9)+2
x=10/9
y=4/9,x=10/9
-2
8(17-12)/ -2(8+2).
A negative and a negative equals a plus
8(5) / -2(10)
40 / -20
= -2

I believe the answer would be 4,5,6.
Step-by-step explanation:
The width is 18.
step by step:
1. 2 lengths are 20 which is 20+20 that's 40.
