Question

Solve the equation. Check your solution.

$\frac{-z}{4}=\frac{-3}{4}$

Answer 1

Step 1 : Solve the inequality

We have,

$\Rightarrow \frac{-z}{4}=\frac{-3}{4}$

$\Rightarrow \frac{-z}{4}\times -4=\frac{-3}{4}\times -4$ [ Multiply both sides by $-4$]

$\therefore z=3$

Step 2 : Checking the solution

Check the solution by putting $z=3$ in the given inequality

We have,

$\Rightarrow \frac{-z}{4}=\frac{-3}{4}$

$$\begin{gathered} \Rightarrow \frac{-3}{4}=\frac{-3}{4} \\ \therefore \mathrm{LHS}=\mathrm{RHS} \end{gathered}$$

Hence, the required solution is $z=3$
