1-6b+7=14 8-6b =14 -6b =6 -b =1 b =-1
6b-14=-7-b 6b+b =-7+14 7b =7 b =1
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
a = 6b = 9a + b = 6 + 9 = 15
12a + 6b + 6c = 6(2a + b + c)
1-6b+7=14 8-6b =14 -6b =6 -b =1 b =-1
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
6b-14=-7-b 6b+b =-7+14 7b =7 b =1
The answer to 6b plus 7 times 5-4b plus 1 equals 38. This is taught in math.

20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
5b - 3 - 2b = 6b - 3 3b - 3 = 6b - 3 3b - 6b = 3 - 3 b = 0

If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42
14
a = 6b = 9a + b = 6 + 9 = 15
4d-2 equals 6b-4
