##### Enter Equation or Inequality

Solve the following equation

10-f+1.5f=12.50

Solve for f

10 - f + 1.5f = 12.50

##### Group the f terms on the left:

(-1 + 1.5)f = 0.5f

##### Form modified equation

0.5f + 10 = + 12.5

##### Group constants

Group our constants 10 and 12.50.
subtract 10 from both sides

0.5f + 10 - 10 = 12.50 - 10

0.5f = 2.5

##### Divide each side of the equation by 0.5

 0.5f 0.5
 =
 2.5 0.5

f = 5

f = 5

f = 5
