Question

Solve for y when 3xy+y=15

Answer 1

you can factor out y from 3xy + y so do that first

Answer 2

take y common..

Answer 3

3xy+y=15
i.e y(3x+1)=15
i.e y=15/(3x+1)

Answer 4

15 -3(15)x + 3(15)x^2-...
---------------
1+3x | 15
- (15+3(15)x)
-----------
-3(15)x
-(-3(15)x-3(3)(15)x^2)
---------------------
3^2(15)x^2

\[y=15\sum_{n=0}^{\infty}~(-3x)^n\]
