    (x.7+8):5=10
    =>7x+8=50
    =>7x=42
    =>x=6
    Vậy x=6
    280:(7+3.x)=4
    =>7+3x=70
    =>3x=63
    =>x=21
    Vậy x=21
    4.(36-4x)=64
    =>36-4x=16
    =>4x=20
    =>x=5
    Vậy x=5
    (x:2+50):5=12
    =>x:2+50=60
    =>x:2=10
    =>x=20
    Vậy x=20
    (x.7+8):5=10
    =>7x+8=50
    =>7x=42
    =>x=6
    Vậy x=6
