4s+5=3s+15

Enter Equation or Inequality

Solve the following equation
4s+5=3s+15

Solve for s
4s + 5 = 3s + 15

Group variables:

Group our variables 4s and 3s
subtract 3s from both sides
4s + 5 - 3s = 3s + 15 - 3s

s + 5 = 15

Group constants:

Group our constants 5 and 15.
subtract 5 from both sides
s + 5 - 5 = 15 - 5

Cancel 5 on the left side:

s = 10

s = 10
