Question
Find the value of each unknown:
7m = m – 3
7m = m – 3
✓
Answer
7m = m – 3
Subtract m from both sides
7m – m = m – 3 – m
⇒ 6m = -3
Divide both sides by 6
$\begin{array}{l}\frac{6 m}{6}=-\frac{3}{6} \\ \Rightarrow m=-\frac{1}{2}\end{array}$
Subtract m from both sides
7m – m = m – 3 – m
⇒ 6m = -3
Divide both sides by 6
$\begin{array}{l}\frac{6 m}{6}=-\frac{3}{6} \\ \Rightarrow m=-\frac{1}{2}\end{array}$
