Answer 2

Solution:-

Let the number be 'x'

According to the question:-

$4x - 11 = 89 \\ \\ 4x = 11 + 89 \\ \\ 4x = 100 \\ \\ x = \frac{100}{4} \\ \\ x = 25$

$\Large \rm \red {Hence, the \: number \: is \: 25.}$

Verification:-

$4x - 11 = 89 \\ \\ 4(25) - 11 = 89 \\ \\ 100 - 11 = 89 \\ \\ \boxed{89 = 89} \\ \\ \rm lhs = rhs \\ \\ \large\rm \red{ Hence, Proved.}$
