**Bosnian**, Wednesday, August 15, 2012 at 2:45am3 ( 5 y - 5 x ) = 45

3 * 5 * ( y - x ) = 3 * 3 * 5

15 ( y - x ) = 3 * 15 Divide both sides by 15

y - x = 3 Add x to both sides

y - x + x = 3 + x

y = x + 3

If you must solve y = 0

0 = x + 3 Subtrac 3 to both sides

0 - 3 = x + 3 - 3

- 3 = x

x = - 3

OR

3 ( 5 y - 5 x ) = 45 Divide both sides by 3

5 y - 5 x = 45 / 3 = 15

5 * 0 - 5 x = 15

- 5 x = 15 Divide both sides by - 5

x = 15 / - 5

x = - 3
