A number is 15 more than thrice a number gives 72. Its linear equation will be ___________ and the number is ____________________________

Answer 1

Answer:

$\pink{\mathcal{SOLUTION}}$

$\blue{\sf \: Let \: a \: number \: be \: x}$

$\green{ \mathbb{ACCORDING \: \: TO \: \: QUESTION }}$

$\blue{\sf \:15 \: more \: than \: thrice \: of \: number = 72}$

$\blue{\sf \implies\:15 + 3x = 72}$

$\blue{\sf \implies\: 3x = 72 - 15}$

$\blue{\sf \implies\: 3x =57}$

$\blue{\sf \implies\: x = \frac{57}{3} }$

$\blue{ \implies\:\boxed{ \sf \: x =19}}$

Answer 2

$Let \: the \: number \: be \: x$

$15 \: more \: than \: thrice \: a \\ number = 72$

$15 + 3x = 72 \\ \\ 3x = 72 - 15 \\ \\ 3x = 57 \\ \\ x = \frac{57}{3} \\ \\ x = 19$
