Question

Solve the equation. Check your solution.

$4x=-8$

Answer 1

Step 1 : Solve the inequality

We have,

$\Rightarrow 4x=-8$

$\Rightarrow \frac{4x}{4}=\frac{-8}{4}$ [ Divide both sides by $4$ ]

$\therefore x=-2$

Step 2 : Checking the solution

Check the solution by putting $x=-2$ in the given inequality

$\Rightarrow 4x=-8$

$$\begin{gathered} \Rightarrow 4\times -2=-8 \\ \Rightarrow -8=-8 \\ \Rightarrow \mathrm{LHS}=\mathrm{RHS} \end{gathered}$$

Hence, the required solution is $x=-2$
