2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
-2x+14=20 -2x=20-14 -2x=6 -2x/-2=6/-2 x=-3
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
2x+3x = 5x
-2x+14=20 x=-3
2 plus 1-x divided by.
8
Because all the terms have been divided by -1
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
2x + y = 20 y = -2x + 20 Slope = -2 m=-2
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
x = 20
it equals 13X.
-2x+14=20 -2x=20-14 -2x=6 -2x/-2=6/-2 x=-3
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
