    Answer:

    7x+6y=3800x +5y(i)*3

    3x+5y=1750(ii)*7

    21x+18y=11400(iii)

    21x+35y=12250(iv)

    on subtracting equation iii from iv we get

    17y=850

    y=50

    Therefore,

    put the value of y=50 in equation i we get

    7x+6*50=3800

    7x+300=3800

    7x=3500

    X=500

    Step-by-step explanation:
