    Giải đáp + Lời giải và giải thích chi tiết:
    g, 140:(x-8)=7
    => x-8=140:7
    => x-8=20
    => x=20+8
    => x=28
    h, 4.(x+41)=400
    => x+41=400:4
    => x+41=100
    => x=100-41
    => x=59
    i, 5.(x-9)=350
    => x-9=350:5
    => x-9=70
    => x=70+9
    => x=79
    j, 2x-49=5.32
    => 2x-49=160
    => 2x=160+49
    => 2x=209
    => x=209:2
    => x=104,5
    k, 200-(2x+6)=43
    => 2x+6=200-43
    => 2x+6=157
    => 2x=157-6
    => 2x=151
    => x=151:2
    => x=75,5
    l, 135-5.(x+4)=35
    => 5.(x+4)=135-35
    => 5.(x+4)=100
    => x+4=100:5
    => x+4=20
    => x=20-4
    => x=16
