Rewrite the equation so that y is the fucntion of x:

a. 1/7(49-7y)=5x-3y+14
b. 4(2x-3y)=-5(x+3y)

Can you please explain and show how to do these two problems? Thank you.

    Combine terms and put y alone on one side of the equation.


    8x - 12y = -5x - 15y

    Add 15y and subtract 8x from both sides.

    3y = -13x

    y = -13x/3

    Do a similar process with the first equation.

    I hope this helps. Thanks for asking.

    Thanks a lot!

    For b, it also says "use the result to find y when x=-1, 0, 2."
    Can you please check this?

    Thanks again!
