Step 1  74=f−48  Multiply both sides by 8.  74×8=f−4  Express 74×8 as a single fraction  7×84=f−4  Multiply 7 and 8 to get 56.  564=f−4  Divide 56 by 4 to get 14.  14=f−4  Swap sides so that all variable terms are on the left hand side.  f−4=14  Add 4 to both sides.  f=14+4  Add 14 and 4 to get 18.  f=18

The solution of the proportion \frac{7}{4}=\frac{f-4}{8}.
