Q. Sharon tried to solve an equation step by step.\newline9=3(e2)9=3e+6 Step 115=3e Step 2  \begin{array}{l} 9=-3(e-2) \\ 9=-3 e+6 \quad \text { Step } 1 \\ 15=3 e \quad \text { Step 2 } \\ \end{array} \newline5=e Step 3  5=e \quad \text { Step 3 } \newlineFind Sharon's mistake.\newlineChoose 11 answer:\newline(A) Step 11\newline(B) Step 22\newline(C) Step3 \operatorname{Step} 3 \newline(D) Sharon did not make a mistake.
  1. Distribute 3-3 to both terms: Sharon starts with the equation 9=3(e2)9 = -3(e - 2). She distributes 3-3 to both ee and 2-2, which should result in 3e+6-3e + 6.\newlineCalculation: 3×e+(3)×(2)=3e+6-3 \times e + (-3) \times (-2) = -3e + 6\newlineMath error check:
  2. Add 99 to both sides: Sharon then adds 99 to both sides of the equation to isolate the term with ee.\newlineCalculation: 9=3e+69 = -3e + 6 becomes 96=3e9 - 6 = -3e, which simplifies to 3=3e3 = -3e.\newlineMath error check:
