To determine

To solve: The equation $7x=-63$ .

Answer to Problem 37CUR

The value of $x$ is $\left(-9\right)$ .

Explanation of Solution

Given information : The equation is $7x=-63$ .

Concept used : First we have to solve the equation then the $x$ substitute by the value of $x$ in the equation to check.

Calculation :

  $\begin{array}{l}7x=-63\\ \Rightarrow x=\frac{-63}{7}\\ \Rightarrow x=-9\end{array}$

Thus, the value of $x$ is $\left(-9\right)$ .

Verification:

Left hand side,

  $\begin{array}{l}7x\\ =7\times \left(-9\right)\\ =-63\end{array}$

Right hand side $=-63$

Therefore, Right hand side = Left hand side.
