Chapter 12.1, Problem 39E

To determine

To solve:The equation,

  $5x-12=38$ for $x$ .

Answer to Problem 39E

The value of the $x$ is $10$ .

Explanation of Solution

Given: The equation is $5x-12=38$ .

Calculation:

Solve the equation for $x$

  $\begin{array}{l}5x-12=38\\ \Rightarrow 5x=38+12\\ \Rightarrow 5x=50\\ \Rightarrow x=\frac{50}{5}\\ \Rightarrow x=10\end{array}$

Thus, the value of the $x$ is $10$ .

Check the solution, put the value of $x$ in the left-hand side of the equation

  $\begin{array}{l}=5\times 10-12\\ =38\end{array}$

  $=$ right hand side of the equation

Hence, the solution is checked.
