Question

Solve the equation. Check your solution.

$4x=36$

Answer 1

Step 1 : Solve the equation

We have,

$$\begin{gathered} \Rightarrow 4x=36 \\ \Rightarrow \frac{4x}{4}=\frac{36}{4}[\mathrm{Dividing}\mathrm{both}\mathrm{sides}\mathrm{by}4] \\ \therefore x=9 \end{gathered}$$

Step 2 : Check the solution

Put the value of $x$ in the given equation

$$\begin{gathered} \Rightarrow 4\times 9=36 \\ \Rightarrow 36=36 \\ \therefore \mathrm{LHS}=\mathrm{RHS} \end{gathered}$$

Hence, the value of $x=9$.
