-20 = -4x - 6x-20 = -10x20 = 10x2 = x

-20=-4x-6x

x=2

x = 2

x = 2

4x-15=6x-4x 4x-22.4=2x 2x=22.4 x=11.2

-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2

If: 6x-6 = 4x Then: x = 3

-20=-4x-6x -20=-10x {collect like terms} x=2 {divide each side by -10}

Add 12 to each side: 4x + 6x = 20 ie 10x = 20 so x = 2

-4x-6x = -20 -10x = -20 Divide both sides by -10 rembering that a minus divided into a minus the result is positive: x = 2

6x + 14 = 20 + 4x ------ Combine like terms (subtract 4x and 14 from both sides). 2x = 6 --------------------- Divide by 2. x = 3
