Chapter 2.5, Problem 1P

Solve each equation for $m$.

Then find the value of $m$ for each value of $n$.

$m+3n=7;n=-2,0,1$

To determine

To find: the value of m for each value of n.

Answer to Problem 1P

  $13,7,4$

Explanation of Solution

Given information:

The given expression is

  $m+3n=2=7;n=-2,0,1$

Calculation:

For n = −2, solve for m

  $\begin{array}{l}m+3\left(-2\right)=7\\ m-6=7\\ m=7+6\\ m=13\end{array}$

For n = 0, solve for m

  $\begin{array}{l}m+3\left(0\right)=7\\ m+0=7\\ m=7+0\\ m=7\end{array}$

For n = 1, solve for m

  $\begin{array}{l}m+3\left(1\right)=7\\ m+3=7\\ m=7-3\\ m=4\end{array}$
