Question
Solve the following equation : $\frac{y}{1.8}-2.1=-2.8$
✓

Answer

$\frac{ y }{1.8}-2.1=-2.8$
$\Rightarrow \frac{ y }{1.8}-2.1+2.1$
$=-2.8+2.1($ Adding  $2.1$  to  both sides $)$
$\Rightarrow \frac{ y }{1.8}=-0.7$
$\Rightarrow \frac{ y }{1.8} \times 1.8$
$=-0.7 \times 1.8($ Multiplying by  $1.8)$
$\therefore y=-1.26$
