Question

find the number which x 8 and then reduced by 9 is equal to 47​

Answer 1

Answer:

here's the answer mark me as brainliest

answer is 7

Step-by-step explanation:

here mate, look

let the number be y.

so, A.T.Q(according to question)

(y × 8) - 9 = 47. (number multiply by 8 and reduced by 9 is equal to 47

to find out the number we need to solve this equation.

we have to form our own equation according to the question.

let's solve the equation to find out the number.

(y × 8) - 9 = 47

8y - 9 + 9 = 47 + 9 ( adding 9 on both sides)

8y = 56

8y/8 = 56/8 ( dividing 8 on both sides)

y = 7 ans.

so the number is 7

Answer 2

Given :

• Find the number which multiplied by 8 and then reduced by 9 is equal to 47.

To Find :

• The required number.

Solution :-

Let the required number be x.

According to the question :

$: \implies { \sf{(x \times 8 ) - 9 = 47 }} \\ \\ : \implies { \sf{8x - 9 = 47 }} \\ \\ : \implies { \sf{8x = 47 + 9 }} \\ \\ : \implies { \sf{8x = 56 }} \\ \\ : \implies { \sf{x = \frac{56}{8} }} \\ \\ : \implies { \boxed {\tt{x = 7 }}}$

$\underline{\bf {\therefore {The\:required\: number\: is \:7.}}}$

Verification :-

We have :

• $\sf{(x \times 8 ) - 9 = 47 }$

Putting the value of x in the equation :

$: \implies {\sf {(x \times 8 ) - 9 = 47}}\\ \\ : \implies {\sf {(7 \times 8 ) - 9 = 47}}\\ \\ :\implies {\sf {56 - 9 = 47}}\\ \\ : \implies {\sf {47 = 47}}\\ \\ : \implies {\boxed{\tt {LHS= RHS}}}$

$\underline{\bf {\therefore {Proved.}}}$
