3x + -1 = 5x + 4

Move the variable to one side. Subtract 5x from both sides OR subtract 3x from both sides.

Solve for x: 18 = 4x + 2
x = 4

What is the first step to solve this? 8x + 2 = 6x - 1

Move the variable to one side. Subtract 8x from both sides OR subtract 6x from both sides.

Solve for x: -3x - 18 = 21
x = -13

What is the first step? 3x - 3 = 4x

Move the variable to one side, so subtract 3x from both sides. -3 = x

Solve for x: 2x + 2 = 5x + 11
x = -3

What is the first step? -5x = -8x - 4

Move the variable to one side. So, add 8x to both sides. 3x = -4

Solve for x: -3 - 4x = 21- 8x
x = 6
