  1. a)
    76,22 – x – 25,7 = 30 + 5,52
    76,22 – x – 25,7 = 3 5,52
    76,22 – x  = 35,52+ 25,7
    76,22 – x  =61,22
    x=76,22-61,22
    x=15
    Vậy x=15
    b)
    25,63 – x : 4 =1, 63
    x : 4 =25,63 – 1, 63
    x : 4 =24
    x  =24xx4
    x=96
    Vậy x=96

  2. $\text{Giải đáp:}$
    $76,22 – x – 25,7 = 30 + 5,52$
    $76,22 – x – 25,7 = 35,52$
    $76,22 – x = 35,52 + 25,7$
    $76,22 – x = 61,22$
    $x = 76,22 – 61,22$
    $x = 15.$
    $——$
    $25,63 – x : 4 = 1, 63$
    $x : 4 = 25,63 – 1,63$
    $x : 4= 24$
    $x = 24×4$
    $x = 96.$
