Answer:
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.
[tex]\frac{f}{3} + 22 = 17[/tex]
[tex]-22[/tex] [tex]-22[/tex]
You should then get this equation:
[tex]\frac{f}{3} = -5[/tex]
Since there is division involved in [tex]\frac{f}{3}[/tex], 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.
[tex]3[/tex] × [tex]\frac{f}{3} = -5[/tex] × [tex]3[/tex]
You should get this equation now:
[tex]f = -5[/tex] × [tex]3[/tex]
Solving it will let you have:
[tex]f = -15[/tex]
To check if your answer is right, replace the variable f with -15 in [tex]\frac{f}{3} + 22 = 17[/tex] and solve.
