Solve the following equation

6(x+3)=42

Solve for x

6(x + 3) = 42

Simplify by removing parentheses
Simplify 6(x + 3):
Distribute the 6 to each term in (x+3)
6 * x = (6 * 1)x = 6x
6 * 3 = (6 * 3) = 18
Our Total expanded term is 6x + 18

Our new term is
6x + 18 = 42

Simplify by removing parentheses
Our new term is
6x + 18 = 42

Group constants

Group our constants 18 and 42.
subtract 18 from both sides

6x + 18 - 18 = 42 - 18

Cancel 18 on the left side:

6x = 24

Divide each side of the equation by 6

6x
6
=
  
24
6

x = 4
