Question
$\frac45-\text{x}=\frac35$
✓
Answer
$\frac45-\text{x}=\frac35$
Subtracting $\frac45$ from both sides, we get
$\frac{4}{5}-\text{x}-\frac45=\frac35-\frac45$
$-\text{x}=\frac35-\frac45$
$-\text{x}=-\frac15$
Dividing both sides by -1, we get
$-\text{x}\times(-1)=-\frac15\times(-1)$
$\text{x}=\frac15$
Verification:
Substituting $\text{x}=\frac15$ in L.H.S., we get
$\text{L.H.S.}=\frac{4}{5}-\frac15=\frac{4-1}{5}=\frac35,$ and $\text{R.H.S.} = \frac35$
L.H.S. = R.H.S.
Hence, verified.
