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

15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
10ab + 15b = 5b (2a + 3)
15b=4 That is the original equation.b=4/15 You need to isolate "b" and the way to do that is to divide 15 from both sides. Thus, b=4/15
15b/39b4 = 5/13*b-3

15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
Re-ordering it : 13a - a -15b + 2b = 12a - 13b
10ab + 15b = 5b (2a + 3)
15b + 13c - 12b + 10c + 8 = 3b + 23c + 8
b + b + b + 7 = 223b + 7 = 223b = 15b = 5
Divide 300 by 15 to get the answer. The answer is 300/15.
In the expression '15b + 23b + 10', the coefficients are 15, 23, and 10.If you simplify the expression to '38b + 10", then the coefficients are 38 and 10.
50 - 3b = 353b = 50 - 353b = 15b = 5
15b=4 That is the original equation.b=4/15 You need to isolate "b" and the way to do that is to divide 15 from both sides. Thus, b=4/15
3 x 5 x b = 15b No exponents required.
15b/39b4 = 5/13*b-3
I can help with that. Would you like a translation of a specific sentence or section from ecce Romani 1 exercise 15b?
