Multiply through by x:
3 - x = 6 + 2x
Solve for x:
3x = -3
x = -1

3 / x - 1 = 6 / x + 2
choose a common denominator which is x and multiply through out you will get
(3 - x - 6 -2x)/x = 0
-3 -3x = 0
x = -1

multiply everything by x and you get
3 - x = 6 + 2x
combine terms
-3 = 3x
divide by 3
x = -1
check:
(3/(-1) - 1 = 6(-1) + 2
-3 -1 = -6 + 2
-4 = -4

Multiply both sides by x:-
3 - x = 6 + 2x
- 3 = 3x
x = - 1

Wow. Glad it is you that has to go to that class. I am so thankful classes like that are over. Do you think that you will remember solving problems like this ten years from now? Many of us never use this type of math in our daily lives. Good luck.
