Question

Solve the equation. Check your solution.

$-2+\mathrm{j}=-22$

Answer 1

Step 1 : Solve the inequality

We have,

$\Rightarrow -2+\mathrm{j}=-22$

$\Rightarrow -2+\mathrm{j}+2=-22+2$ [ Add$2$ both sides ]
$\therefore \mathrm{j}=-20$

Step 2 : Checking the solution

Check the solution by putting $\mathrm{j}=-20$ in the given inequality

We have,

$\Rightarrow -2+(-20)=-22$

$$\begin{gathered} \Rightarrow -2-20=-22 \\ \Rightarrow -22=-22 \\ \Rightarrow \mathrm{LHS}=\mathrm{RHS} \end{gathered}$$

Hence, the required solution is $\mathrm{j}=-20$.
