9b-13b= -4b -4b = 40 Divide both sides by -4 b = -10
Gh
15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
3A + 9B = 3(A + 3B)
10b
9b-13b= -4b -4b = 40 Divide both sides by -4 b = -10
Gh
15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
9b + 6 - 8 = -36 9b = -38 b = 4.2222222(repeating)
3A + 9B = 3(A + 3B)
The simplified expression is -9a -9b.
6B, 7B, 8B, 9B, 10B, 11B, 12B, 13B, 14B, 15B, 16B, 17B, 18B, 19B
There are 3 terms in the given expression of 6a+9b+15
10b
You would factor 3a + 9b as: 3(a+3b)
All the terms in b add to 11, so 11b = 132 making b = 12
(6ab + 9b)/(2a + 3) = 3b(2a + 3)/(2a + 3) = 3b
