  1. a) x + 5,34 = 7,65 
    x=7,65-5,34
    x=2,31
    b)7,95 + x = 10,29
    x=10,29-7,95
    x=2,34
    c)x – 3,78 = 6,49
    x=3,78+6,49
    x=10,27
    d)8,4 – x = 3,6
    x=8,4-3,6
    x=4,8

  2. a) x + 5,34 = 7,65
    x=7,65-5,34
    x=2,31

    b)7,95 + x = 10,29
    x=10,29-7,95
    x=2,34
