Question
Solve : $\frac{b}{1.6}+3=-2.5$
✓
Answer
$\frac{ b }{1.6}+3=-2.5$
$\Rightarrow \frac{ b }{1.6}=-2.5-3$
$\Rightarrow \frac{ b }{1.6}=-5.5$
$\Rightarrow b =-5.5 \times 1.6$
$\Rightarrow b =-8.80$
$\Rightarrow \frac{ b }{1.6}=-2.5-3$
$\Rightarrow \frac{ b }{1.6}=-5.5$
$\Rightarrow b =-5.5 \times 1.6$
$\Rightarrow b =-8.80$
