Vanessa tried to solve an equation step by step.
\qquad\begin{aligned} -12& =4(f-6) \\ -12& =4f-24& \green{\text{step } 1} \\ 12& =4f& \blue{\text{step } 2} \\ 4& =f& \purple{\text{step } 3} \end{aligned}
−12
−12
12
4


=4(f−6)
=4f−24
=4f
=f


step 1
step 2
step 3

Add 1/7 + -1/7 your answer should be reduced to its smallest form and should not be an improper fraction
