Rewrite the equation so that y is the fucntion of x:
a. 1/7(497y)=5x3y+14
b. 4(2x3y)=5(x+3y)
Can you please explain and show how to do these two problems? Thank you.

PsyDAG,
Combine terms and put y alone on one side of the equation.
4(2x3y)=5(x+3y)
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.

Kat,
Thanks a lot!
For b, it also says "use the result to find y when x=1, 0, 2."
Can you please check this?
f(1)=y=13/3
f(0)=y=0/3
f(1)=y=13/3
Thanks again!

Kat,
The last one should say:
f(2)=y=26/3
