Two-step equations

Reorder the terms: 30 = 5(1 + x)

                               30 = (1 * 5 + x * 5)

                               30 = (5 + 5x)

Solving: 30 = 5 + 5x

Solving for variable 'x'.:

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation. 30 + -5x = 5 + 5x + -5x

Combine like terms: 5x + -5x = 0

                                   30 + -5x = 5 + 0

                                   30 + -5x = 5

Add '-30' to each side of the equation. 30 + -30 + -5x = 5 + -30

Combine like terms: 30 + -30 = 0

                                   0 + -5x = 5 + -30

                                  -5x = 5 + -30

Combine like terms: 5 + -30 = -25

-5x = -25 

Divide each side by 5: x = 5

Answer: x = 5

Here's another option :

30  = 5 (x + 1)    divide both sides by 5

6  = x + 1     subtract 1 from both sides

5 = x
