Answer 1

Hello mate..

Question: ⤋

Find the number who is three time subtracted from 9 it become 12.

Answer: ⤋

Let the number be 'x'.

Three times a number subtracted from 9 = 3x - 9.

3x - 9 = 12

3x = 12 + 9

3x = 21

$x \: = \: \frac{21}{3}$

x = 7

Therefore, the number is 7.

Proof: 3(7) - 9 = 12
