Question
Solve: $\frac{ z }{3}-1=-5$
✓
Answer
$\frac{ z }{3}-1=-5$
$\Rightarrow \frac{ z }{3} \times 3-1 \times 3=-5 \times 3$
$\Rightarrow z - 3 = - 15$
$\Rightarrow z = - 15 + 3$
$\Rightarrow z = - 12$
$\Rightarrow \frac{ z }{3} \times 3-1 \times 3=-5 \times 3$
$\Rightarrow z - 3 = - 15$
$\Rightarrow z = - 15 + 3$
$\Rightarrow z = - 12$
