Question
$x - 1 =$ _______ ; when $2x = 2.$
✓
Answer
Given that, $2\text{x}=2$
$\Rightarrow\frac{2\text{x}}{2}=\frac{2}{2} [$dividing both sides by $2]$
$\Rightarrow\text{x}=1$
$\therefore\text{x}-1=1-1=0$
$\Rightarrow\frac{2\text{x}}{2}=\frac{2}{2} [$dividing both sides by $2]$
$\Rightarrow\text{x}=1$
$\therefore\text{x}-1=1-1=0$
