$\bf{\huge{\underline{\boxed{\sf\purple{Answer:7}}}}}$

$\huge\underline{\underline{\tt Explanation:}}$

$\sf{\pink{\underline{Given:}}}$

• A number when multiplied by 8 and then  reduced  by 9, it becomes 47

$\sf{\pink{\underline{To\:Find:}}}$

• The unknown number.

$\textbf{\underline{\underline{Solution:}}}$

Let the number be ' x ' . The equation will be :  8x - 9 = 47.

Now,

$\textsf{\underline{\large{According\:to\:Question:}}}$

8x - 9 = 47

→ 8x = 47 + 9

→ 8x = 56

→ $x =\dfrac{56}{8}$

∴ x = 7

Hence,

The unknown number is 7.

$\huge\star\underline\mathscr\green{Verification:}$

→ 8x - 9 = 47

Put the value of x in the  equation,

→ ( 8 × 7 ) - 9 = 47

→ 56 - 9 = 47

→ 47 = 47

∴ L.H.S = R.H.S

Hence, Proved!
