To determine

To calculate: Find the value of $x$

for the equation $3x-8=23$.

Answer to Problem 1RE

Solution:

The value of $x$

is $\frac{31}{3}$.

Explanation of Solution

Given Information:

The given equation is $3x-8=23$.

Calculation:

To solve the equation for $x$, add 8 on both sides.

$\begin{array}{c}3x-8+8=23+8\\ 3x=31\end{array}$

Divide the expression on both sides by $3$.

$\begin{array}{c}\frac{3x}{3}=\frac{31}{3}\\ x=\frac{31}{3}\end{array}$

Hence, the required value of $x$

is $\frac{31}{3}$.
