Question

Solve the equation. Check your solution.

$5b-3=22$

Answer 1

Step 1:

$$\begin{gathered} 5b-3=22 \\ 5b=22+3 \\ 5b=25 \end{gathered}$$

Step 2:

$$\begin{gathered} b=\frac{22}{5} \\ b=5 \end{gathered}$$

Step 3: Check substitute $b=5$ in $5b-3=22$

$$\begin{gathered} LHS\Rightarrow 5b-3=22 \\ \Rightarrow (5\times 5)-3=22 \\ \Rightarrow 25-3=22=RHS \end{gathered}$$

Final Answer: $b=5$
