l 10-f+1.5f=12.50
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

Divide each side by 10

10f
10
=
  
1.5
10

Group constants

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

0.5f + 10 - 10 = 12.50 - 10

Cancel 10 on the left side:

0.5f = 2.5

Divide each side of the equation by 0.5

0.5f
0.5
=
  
2.5
0.5

f = 5

Final Answer


f = 5
