    Trả lời:
    yxx40%+y:25%+y=134,298
    =>yxx40%+yxx100/25+yxx1=134,298
    =>yxx(40%+100/25+1)=134,298
    =>yxx5,4=134,298
    =>y=134,298:5,4
    =>y=24,87
    $\text{Vậy}$ y=24,87

    Answer
    y xx 40% + y : 25% + y = 134,298
    y xx 2/5 + y : 1/4 + y = 134,298
    y xx 2/5 + y xx 4 + y xx 1 = 134,298
    y xx (2/5 + 4 + 1) = 134,298
    y xx (22/5 + 1) = 134,298
    y xx 27/5 = 134,298
    y xx 5,4 = 134,298
    y = 134,298 : 5,4
    y = 24,87
