Dr. Robert can help you with Math and Science

Carlton's advice is a good way to get this problem started. I will start where he left off.

3y -6 = 5 -15y

We want the y's on one side of the equal sign and everything else on the other side. I will put the y's on the left. Add 15 y to both sides. (What you do to one side, you must do to the other.)

3y -6 +15y= 5 -15y+15y

18y -6=5

Adding 15y had the effect of moving all the y terms to the left side. Noe add 6 to both sides.

18y -6 +6 =5+6

18y=11

Now divide both sides by 18.

18y/18=11/18

Y=11/18 (Answer)

To check, write the original problem, but put 11/18 in for y. If the equation is true, then the answer is correct.

Y/5-2/5=1/3-y

(11/18)/5 -2/5=1/3-11/18

11/90-2/5=1/3-11/18

11/90-36/90=6/18-11/18

-25/90=-5/18

-5/18=-5/18 TRUE

Since the equation is true, our answer y=11/18 is correct.

Thanks for finishing it :-)
