Chapter 8.1, Problem 62S

To determine

To calculate: To evaluate the expression if $a=12$ and $b=8$

Answer to Problem 62S

Expression is equal to $0$

Explanation of Solution

Given information: Expression is $3b-2a$

Calculation:

Expression is given as follows:

  $3b-2a$

Here,

  $\begin{array}{l}a=12\\ b=8\end{array}$

Substituting the value in above expression,

  $\begin{array}{l}3b-2a=3\left(8\right)-2\left(12\right)\\ 3b-2a=24-24\\ 3b-2a=0\end{array}$

Hence, on evaluation, expression is equal to $0$
