$\large\mathfrak \pink{Solution:-}$

$\underline \mathbb{TO \: FIND:-}$

$★ \boxed{The \: Equation}$

$\underline \mathbb{ASSUMPTION:-}$

$\boxed{Let \: , \: the \: number \: be \: x}$

$\underline \mathbb{BY \: THE \: PROBLEM:-}$

$4x - 15 = 65$

$\underline \mathbb{ANSWER:-}$

$\boxed{4x - 15 = 65}$

$\large\mathbb \pink{SOLUTION:-}$

$4x - 15 = 65 \\ \\ \implies \: 4x = 65 + 15 \\ \\ \implies \: 4x = 80 \\ \\ \implies \: x = \frac{80}{4 } \\ \\ \implies \: x \: = 20$

$\underline \mathbb{VERIFICATION:-}$

$4 x - 15 = 65 \\ \\ \implies( \: 4 \times 20) \: - 15 = 65 \\ \\ \implies \: 80 - 15 = 65 \\ \\ \implies \: 65 = 65$

$\mathfrak{ \boxed{Hence \: Proved}}$
