    Step-by-step explanation:

    y=x+3

    y=4x

    Substitute the second equation into the first equation

    4x = x+3

    Subtract x from each side

    4x-x = x-x+3

    3x = 3

    Divide each side by 3

    3x/3 = 3/3

    x = 1

    Now we need to find y

    y = 4x

    y = 4*1

    y=4
