12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
5b - 3 - 2b = 6b - 3 3b - 3 = 6b - 3 3b - 6b = 3 - 3 b = 0

The answer to 6b plus 7 times 5-4b plus 1 equals 38. This is taught in math.
4d-2 equals 6b-4
a = 6b = 9a + b = 6 + 9 = 15
6B = 1446B/6 = 144/6B = 24Double Check your Answer6B = 1446(24) = 144144 = 144So 6B = 144 when B = 24.
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
5b - 3 - 2b = 6b - 3 3b - 3 = 6b - 3 3b - 6b = 3 - 3 b = 0
6b-14=-7-b 6b+b =-7+14 7b =7 b =1
If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42

1-6b+7=14 8-6b =14 -6b =6 -b =1 b =-1
The GCF is 3.
It would be composite because a=1 and b=5 so it would be 3+1+6+5=15, and 15 can be divided by 3 into 5.
