Solve the following equation

60b+1500=80b

Solve for b

60b + 1500 = 80b

Group variables

Group our variables 60b and 80b
subtract 80b from both sides

60b + 1500 - 80b = 80b - 80b

Cancel 80b on the right side:

-20b + 1500 = 0

Group constants

Group our constants 1500 and 0.
subtract 1500 from both sides

-20b + 1500 - 1500 = 0 - 1500

Cancel 1500 on the left side:

-20b = -1500

Divide each side of the equation by -20

-20b
-20
=
  
-1500
-20

b = 75

Final Answer

b = 75
