Answer 2

Step-by-step explanation:

$let \: the \: number \: be \: = x$

$5x = 3(x + 4) \: \: \: (according \: to \: the \: question \: we \: created \: a \: equation)$

$5x = 3x + 12 \: \: (multiplying \: by \: 3)$

$\frac{3x + 12}{5x} \: \: (sending \: 5x \: to \: r.h.s )$

$\frac{3 + 12}{5} \: (x \: and \: x \: cancelled)$

$\frac{15}{5}$

$3 \: is \: the \: answer$
