Solve the following equation

0.5p+21=61.50

Solve for p

0.5p + 21 = 61.50

Group constants

Group our constants 21 and 61.50.
subtract 21 from both sides

0.5p + 21 - 21 = 61.50 - 21

Cancel 21 on the left side:

0.5p = 40.5

Divide each side of the equation by 0.5

0.5p
0.5
=
  
40.5
0.5

p = 81
