Question

Four times a number reduced by $5$ equals $19$. Find the number.

Answer 1

If the number is taken to be '$x$'
Then four times of the number is '$4x$'
When it is reduced by $5$ it equals to $19$
$\Rightarrow$ $4x-5=19$
$4x=19+5$ (Transposing $-5$ to RHS)
$4x=24$
$\therefore$ $x=\frac{24}{4}$ (Transposing $4$ to RHS)
$\Rightarrow$ $x=6$
Hence the required number is $6$.
