Question

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

Answer 1

Answer:

Yusuf's mistake is from Step 1

$\text{ Step 1}$

Explanation:

Given the equation;

$\frac{1}{4}r+2=10$

for the first step let us subtract 2 from both sides;

$\begin{gathered} \frac{1}{4}r+2-2=10-2 \\ \frac{1}{4}r=8\text{ ---Step 1} \end{gathered}$

To solve further, let us multiply both sides by 4;

$\begin{gathered} \frac{1}{4}r\times4=8\times4 \\ r=32\text{ ------Step 2} \end{gathered}$

Therefore, Yusuf's mistake is from Step 1

$\text{ Step 1}$
