Answer 1

$\huge\tt\underline{Answer!!!}$

$\mathtt{Let \: the \: number \: be \: x}$

$\fbox{4x \: - \: 11 = \: 89}$

$\longrightarrow$ $\mathtt{4x \: - \: 11 \: = \: 89}$

$\longrightarrow$ $\mathtt{4x \: = \: 89 \: + \: 11}$

$\longrightarrow$ $\mathtt{4x \: = \: 100}$

$\longrightarrow$ $\mathtt{x \: = \: 100/4}$

$\longrightarrow$ $\mathtt{x \: = \: 25}$

Answer 2

Answer:

25

Step-by-step explanation:

let the number be x

now

4x - 11 = 89

4x = 89+11

x = 100/4

x = 25

Proof

4×25 -11 = 89
