Chapter 12, Problem 41CUR

To determine

To solve: The equation $5\left(x+4\right)=60$ .

Answer to Problem 41CUR

The value of $x$ is $8$ .

Explanation of Solution

Given information : The equation is $5\left(x+4\right)=60$ .

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

Calculation :

  $\begin{array}{l}5\left(x+4\right)=60\\ \Rightarrow 5x+20=60\\ \Rightarrow 5x=60-20\\ \Rightarrow 5x=40\\ \Rightarrow x=\frac{40}{5}\\ \Rightarrow x=8\end{array}$

Thus, the value of $x$ is $8$ .

Verification:

Left hand side,

  $\begin{array}{l}5\left(x+4\right)\\ =5\left(8+4\right)\\ =5\times 12\\ =60\end{array}$

Right hand side $=60$

Therefore, Right hand side = Left hand side.
