    Answer:

    y=21/5, x=7/10

    Step-by-step explanation:

    Substitute y=6x

    4x=6x=7

    Simplify 4x+6x

    10x=7

    isolate x for 10x=7:

    10x=7

    Divide both sides by 10:

    10x/10=7/10

    Simplify:

    x=7/10

    For y=6x substitute x=7/10

    y=6*7/10

    Convert element to fraction:

    6/1*7/10

    Cross- cancel common factor:2

    3/1*7/5

    Multiply fractions:

    3*7/1*5

    Multiply the numbers:3*7=21

    =21/5

    y=21/5

    The solutions to the systems of equations are:

    y=21/5,x=7/10
