2x-4 = 20 2x = 20+4 2x = 24 x = 12
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
-2x+14=20 x=-3
To find x -2x = 20 divide both sides by negative 2 -2x/-2 = 20/ -2 x = -10
x = 20
2x-4 = 20 2x = 20+4 2x = 24 x = 12
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
-2x+14=20 x=-3
x=20
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
To find x -2x = 20 divide both sides by negative 2 -2x/-2 = 20/ -2 x = -10
2x - 5 = 15 2x = 20 x = 10
what is the solution of x-5y=10 and 2x-10y=20
-2x+14=20 -2x=20-14 -2x=6 -2x/-2=6/-2 x=-3
x = 20
That doesnt make sense 2x + 8 = 20 Then x = 6
2x+4 = -16 2x = -16-4 2x = -20 x = -10
