I think of a number, subtract 23 and then divide by 8. The answer is 6. What was my starting number?

1. Bosnian

( x - 23 ) / 8 = 6

Multiply both sides by 8

x - 23 = 8 * 6

x - 23 = 48

x - 23 + 23 = 48 + 23

x = 71

( x - 23 ) / 8 = ( 71 - 23 ) / 8 = 48 / 6 = 6

2. Bosnian

My typo.

( x - 23 ) / 8 = ( 71 - 23 ) / 8 = 48 / 8 = 6

3. Anonymous

(×-23)/8=6
(×-23)= 8x6
(×-23)= 48
Transposition method
(×-23)= 48+23
× = 71
(71-23)= 48 ÷ 8 = 6
And. 71 is starting number.

Thanks for helping
