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

  • Math -

    ( 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

  • Math -

    My typo.

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

  • Math -

    (×-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
