Question
Give the step you will use to separate the variable and then solve the equation:
$5m + 7 = 17$
✓
Answer
The given equation is
$5m + 7 = 17$
Subtract 7 from both sides,
$5m + 7 – 7 = 17 – 7$
$5m = 10$
Divide both sides by $5,$
$\frac{5 m}{5}=\frac{10}{5}$
$\therefore m = 2$
It is the required solution.
