Question

Solve the equation. Check your solution.

$\mathrm{l}+15.2=-4.5$

Answer 1

Step 1 : Solve the inequality

We have,

$\Rightarrow \mathrm{l}+15.2=-4.5$

$\Rightarrow \mathrm{l}+15.2–15.2=-4.5–15.2$ [ Subtract $15.2$ from both sides ]
$\therefore \mathrm{l}=-19.7$

Step 2 : Checking the solution

Check the solution by putting $\mathrm{l}=-19.7$, in the given inequality;

$$\begin{gathered} \Rightarrow -19.7+15.2=-4.5 \\ \Rightarrow -4.5=-4.5 \\ \Rightarrow \mathrm{LHS}=\mathrm{RHS} \end{gathered}$$

Hence, the required solution is $\mathrm{l}=-19.7$.
