Solve the following equation

5(s+120)=7s

Solve for s

5(s + 120) = 7s

Simplify by removing parentheses
Simplify 5(s + 120):
Distribute the 5 to each term in (s+120)
5 * s = (5 * 1)s = 5s
5 * 120 = (5 * 120) = 600
Our Total expanded term is 5s + 600

Our new term is
5s + 600 = 7s

Simplify by removing parentheses
Our new term is
5s + 600 = 7s

Group variables

Group our variables 5s and 7s
subtract 7s from both sides

5s + 600 - 7s = 7s - 7s

Cancel 7s on the right side:

-2s + 600 = 0

Group constants

Group our constants 600 and 0.
subtract 600 from both sides

-2s + 600 - 600 = 0 - 600

Cancel 600 on the left side:

-2s = -600

Divide each side of the equation by -2

-2s
-2
=
  
-600
-2

s = 300
