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

Answer:
TRUE
Step-by-step explanation:
2x + 0.8/y = z – 4
x = 7, y = 0.2, z = 22
2×7 + 0.8/0.2 = 22 - 4
14 + 4 = 18
18 = 18
TRUE.
