Question

Solve the equation. Check your solution.

$-10=2\mathrm{y}$

Answer 1

Step 1 : Solve the inequality

We have,

$\Rightarrow -10=2y$

$\Rightarrow \frac{-10}{2}=\frac{2y}{2}$ [ Divide both sides by $2$]

$\Rightarrow -5=\mathrm{y}$

Step 2 : Checking the solution

Check the solution by putting $\mathrm{y}=-5$ in the given inequality;

$$\begin{gathered} \Rightarrow -10=2\times -5 \\ \Rightarrow -10=-10 \\ \text{⇒ LHS = RHS} \end{gathered}$$

Hence, the required solution is $\mathrm{y}=-5$
