Question

Solve for $x$ in the eqaution: $\frac{x}{3}+1=\frac{7}{15}$

Answer 1

$\frac{x}{3}+1=\frac{7}{15}$
$\Rightarrow \frac{x}{3}+1-1=\frac{7}{15}-1$ [Subtracting 1 from both sides]
$\Rightarrow \frac{x}{3}=\frac{7-15}{15}$
$\Rightarrow \frac{x}{3}=\frac{-8}{15}$
$\Rightarrow \frac{x}{3}\times 3=\frac{-8}{15}\times 3$ [Multiplying both sides by 3]
$\Rightarrow x=\frac{-8}{5}$
