12b - 5 = 15b + 5
subtract 12b from both sides
12b - 12b - 5 = 15b - 12b + 5
- 5 = 3b + 5
subtract 5 from each side
- 5 - 5 = 3b + 5 - 5
- 10 = 3b
divide both sides integers by 3
- 10/3 = (3/3)b
- 10/3 = b
---------------------check in original equation ( change whole numbers to fractions of common denominations )
12(-10/3) - 15/3 = 15(-10/3) + 15/3
- 120/3 - 15/3 = - 150/3 + 15/3
- 45 = - 45
