  1. 25 – (7 – x) = 2^3 * 4
    25 – (7 – x) = 8 * 4
    25 – (7 – x) = 32
    7 – x = 25 – 32
    7 – x = -7
    x = 7 – (-7)
    x = 7 + 7
    x = 14
    Vậy x = 14
     

  2. Answer
    25 – (7 – x) = 2^3 . 4
    => 25 – (7 – x) = 8 . 4
    => 25 – (7 – x) = 32
    => (7 – x) = 25 – 32
    => 7 – x = -7
    => x = 7 + 7
    => x = 14
    Vậy x = 14
