Question

Solve the equation. Check your solution.

$-6.8w=3.4$

Answer 1

Step 1 : Solving the equation

We have,

$\Rightarrow -6.8w=3.4$

$\Rightarrow \frac{-6.8w}{-6.8}=\frac{3.4}{-6.8}$ [ Divide both sides by $-6.8$ ]

$\Rightarrow w=\frac{-1}{2}$
$\therefore w=-0.5$

Step 2 : Checking the solution

Check the solution by putting $w=-0.5$ in the given inequality

We have,

$\Rightarrow -6.8w=3.4$

$$\begin{gathered} \Rightarrow -6.8\times -0.5=3.4 \\ \Rightarrow 3.4=3.4 \\ \Rightarrow \mathrm{LHS}=\mathrm{RHS} \end{gathered}$$

Hence, the required solution is $w=-0.5$
