Enter Equation or Inequality

Solve the following equation

0.105f+50=20f+30

Solve for f

0.105f + 50 = 20f + 30

Group variables

Group our variables 0.105f and 20f
subtract 20f from both sides

0.105f + 50 - 20f = 20f + 30 - 20f

Cancel 20f on the right side:

-19.895f + 50 = 30

Divide each side by 0.105

0.105f
0.105
=
  
50
0.105

Group constants

Group our constants 50 and 30.
subtract 50 from both sides

-19.895f + 50 - 50 = 30 - 50

Cancel 50 on the left side:

-19.895f = -20

Divide each side of the equation by -19.895

-19.895f
-19.895
=
  
-20
-19.895

f = 1.0052777079668

Final Answer


f = 1.0052777079668
