Answer
$x=-2.8$
Work Step by Step
Use the Multiplication Property of Equality by multiplying $-2$ to both sides of the equation:
$$\begin{align*}
\left[x\div(-2)\right]\times (-2)&=1.4\times (-2)\\
x&=-2.8\end{align*}$$
Check the solution by substituting $-2.8$ to the variable in the given equation:
$$\begin{align*}
x\div(-2)&=1.4j\\
-2.8\div (-2)\stackrel{?}{=}1.4\\
1.4&\stackrel{\checkmark}{=}1.4\end{align*}$$
Thus, the solution is $x=-2.8$.
