Question

12 reduced from thrice a number gives 27. Find the number.​

Answer 1

Solution:-

Let the no be 'x'

$\implies \tt 3x - 12 =27 \\ \implies \tt3x = 27 - 12$

$\tt \implies 3x = 15 \\ \tt \implies x = \dfrac{15}{3}$

$\tt \implies x = \dfrac{ \cancel{15} { \: \: }^{5} }{ \cancel3 { \: }^{1} }$
