    Answer:

    heya mate ☺

    3x + 4y = 253 \\ putting \: the \: value \: of \: y  \\ =  > 3x + 4(5x) = 253 \\  =  > 3x + 20x = 253 \\  =  > 23x = 253 \\  =  > x = 253  \div  23 \\  =  > x = 11

    y  = 5x \\ putting \: the \: value \: of \: x \\  =  > y = 5(11) \\   = > y = 55

    hope it helps u

    Answer:

    x=11 and y=55

    Step-by-step explanation:

    given,

    y=5x………..(1)

    substituting (1) in equation,

    3x+4(5x)=253

    3x+20x=253

    23x=253

    x=\frac{253}{23}

    x=11………..(2)

    substituting (2) in (1)

    y=5(11)

    y=55
