  1. Giải đáp:
    $x + 13 = 42 + 15$
    $x + 13 = 57$
    $x = 57 – 13$
    $x = 44$
    $—$
    $x + 12 = 36 – 20$
    $x + 12 = 16$
    $x = 16 – 12$
    $x = 4.$
    $—$
    $x + 24 = 42 + 30$
    $x + 24 = 72$
    $x = 72 – 24$
    $x = 48$
    $—$
    $x – 10 = 3 × 4$
    $x – 10 = 12$
    $x = 12 + 10$
    $x = 22$
     

  2. Gửi cậu nò (❁´◡❁)
    x+13=42+15
    =>x+13=57
    =>x=57-13
    =>x=44
    Vậy x=44
    $\\$
    x+12=36-20
    =>x+12=16
    =>x=16-12
    =>x=4
    Vậy x=4
    $\\$
    x+24=42+30
    =>x+24=72
    =>x=72-24
    =>x=48
    Vậy x=48
    $\\$
    x-10=3xx4
    =>x-10=12
    =>x=12+10
    =>x=22
    Vậy x=22
