    Answer:

    x=1, y= 4

    Step-by-step explanation:

    3x + 5y = 23

    y = 4x

    Substitute 4x for y in the first equation

    3x + 5(4x) = 23

    Now we solve for x

    3x+ 20x=23

    Combine like terms

    23x= 23

    Divide both sides by 23

    x=1

    Now we find out y , plug in 1 for x in y=4x

    y=4(1)= 4

    x=1, y= 4
