2x/3=x/2+20 (2x/3=x/2+20)6 4x=3x+120 4x-3x=120 x=120
80=4x, z=6x. find Z. x=80/4, x=20. z=6x20 z=120 answer= 120
4x-7=5x-2 x=-5
4x times 4x equals 16x2.
If: 4x+(-12) = 8 then 4x = 20 and x = 5
If 4x=120, x=30.

80=4x, z=6x. find Z. x=80/4, x=20. z=6x20 z=120 answer= 120
y equals 4x+1 is a parallel line to y equals 4x.

4x2-4x-120 = (2x+10)(2x-12) when factored
4x + 120 = 180 so x = 15
4x2-4x-120 = (2x+10)(2x-12) when factored
2x+y=-12-4x-2y=30 x=-y/2+30, you plug this into -12-4x-2y=30 and get -12+2y-120-2y=30 which gives 2y-2y=162. This is not possible, so the equation is unsolvable.
