Question
If $3 - x = -4,$ then $x =$ _______.
✓
Answer
Given that, $3 - x = -4$
$\Rightarrow -x = -4 - 3 [$transposing $3$ to $RHS]$
$\Rightarrow -x = -7$
$\Rightarrow x = 7 [$multiplying both sides by $(-1)]$
$\Rightarrow -x = -4 - 3 [$transposing $3$ to $RHS]$
$\Rightarrow -x = -7$
$\Rightarrow x = 7 [$multiplying both sides by $(-1)]$
