Question

is m = 12 a solution of 3m = 30 yes or no

Answer 1

We can check if m=12 is a solution to the expression by replacing m with the value 12:

$\begin{gathered} 3m=30 \\ 3(12)=30 \\ 36\ne30 \end{gathered}$

As the expression does not end in an identity (like 30=30, for example), m=12 is not a solution to the expression.

Answer: No, m=12 is not a solution.
