The algebraic expression is obtained from verbal expression using mathematical operators like addition $+$, subtraction $-$, multiplication $×$, division $÷$ and many such more and variable.

In any expression or equation, the variable is an unknown quantity. It may be any alphabet or any special symbol.

In the expression $4x+1$, the unknown quantity is x. So, the variable in this expression is x. 4 and 1 are constants values.

Consider the provided verbal expression.

The product of $\left(2+3\right),\left(3+4\right),\left(4+5\right)$ is equal to three times the sum of 40 and x.

The mathematical operators corresponding to product ismultiplication $×$ and to times is multiplication $×$.

Express the verbal expression as provided below.

$\begin{array}{c}\left(2+3\right)×\left(3+4\right)×\left(4+5\right)=3\left(40+x\right)\\ 5×7×9=3\left(40+x\right)\\ 315=120+3x\end{array}$

Simplify the expression for the value of x.

$\begin{array}{c}315−120=3x\\ 195=3x\\ x=\frac{195}{3}\\ x=65\end{array}$

Hence, the value of x is 65.
