Question

A. Step 1 B. Step 2 C. Omar did not make a mistake

Answer 1

To find out if Omar made a mistake, we must solve the equation step by step.

Step 1

`\begin{gathered} 3x=4.5 \\ \text{divide through by 3} \\ (3x)/(3)=(4.5)/(3) \end{gathered}`

Step 2

Simplify the final part in step 1

`\begin{gathered} (3x)/(3)=(4.5)/(3) \\ x=(3)/(2)=1.5 \end{gathered}`

Since, we have gone through all the steps and gotten exactly the same steps and solution as Omar, we can conclude that Omar did not make a mistake.
