Multiply 3 on both sides.

Step-by-step explanation:

Subtract 22 on both sides so that the positive 22 can be canceled out and that the variable and one other number is left.

You should then get this equation:

Since there is division involved in , multiply both sides by three (Hint: Opposite of division is multiplication!) so that 3 would cancel out and that only the variable f is left.

× ×

You should get this equation now:

×

Solving it will let you have:

To check if your answer is right, replace the variable f with -15 in and solve.
