Answer:
Sharon made a mistake in step 2.
Step-by-step explanation:
Sharon tried to solve an equation step by step.
[tex]\qquad\begin{aligned} 9&=-3(e-2)\\\\ \\ 9&=-3e+6&\green{\text{Step } 1}\\\\ \\ 15&=3e&\blue{\text{Step } 2}\\\\ \\ 5&=e&\purple{\text{Step } 3}\\\\ \end{aligned}[/tex]
The correct steps are:
The given equation is
[tex]9=-3(e-2)[/tex]
Step 1: Using distributive property we get
[tex]9=-3e-3(-2)[/tex]
[tex]9=-3e+6[/tex]
Step 2: Subtract 6 from both sides.
[tex]9-6=-3e+6-6[/tex]
[tex]3=-3e[/tex]
Step 3: Divide both sides by -3.
[tex]\frac{3}{-3}=\frac{-3e}{-3}[/tex]
[tex]-1=e[/tex]
Therefore, Sharon made a mistake in step 2.
