    formula for the specified variable

    solve for y:

    6x-2y=18

    I got Y= 18-6x
    -2

    not sure if thats right or if it's a +2?

    Thank you in advance

    6x-2y=18

    -2y=18-6x

    y=\frac{18-6x}{-2}

    y=-9+3x

    y=3x-9

    It should be a negative 2 you divide by...if you divided by positive 2, then you would be left with -y=\frac{18-6x}{2} then you would just end up dividing through by negative one.

    Then you can simplify further and divide 18 and 6 by negative two to get rid of the fraction.

    Looks good!
