To find out if Omar made a mistake, we must solve the equation step by step.
Step 1
[tex]\begin{gathered} 3x=4.5 \\ \text{divide through by 3} \\ \frac{3x}{3}=\frac{4.5}{3} \end{gathered}[/tex]
Step 2
Simplify the final part in step 1
[tex]\begin{gathered} \frac{3x}{3}=\frac{4.5}{3} \\ x=\frac{3}{2}=1.5 \end{gathered}[/tex]
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.
