Question

Find the value of following expressions given that $\mathrm{m}=2\mathrm{and}\mathrm{n}=-1$

$6\mathrm{m}+2\mathrm{n}$

Answer 1

Step 1: Substituting the values $\mathrm{m}=2\mathrm{and}\mathrm{n}=-1$

$$\begin{gathered} =6\left(2\right)+2(-1) \\ =12-2 \\ =10 \end{gathered}$$

Step 2: Hence the value is 10.
