( x - 23 ) / 8 = 6
Multiply both sides by 8
x - 23 = 8 * 6
x - 23 = 48
Add 23 to both sides
x - 23 + 23 = 48 + 23
x = 71
( x - 23 ) / 8 = ( 71 - 23 ) / 8 = 48 / 6 = 6
I think of a number, subtract 23 and then divide by 8. The answer is 6. What was my starting number?

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