It is: 7b+10 simplified
6B, 7B, 8B, 9B, 10B, 11B, 12B, 13B, 14B, 15B, 16B, 17B, 18B, 19B
6B, 7B, 8B, 9B, 10B, 11B, 12B, 13B, 14B, 15B, 16B, 17B, 18B, 19B
(-a-7b+5)4ab
11a+7b-(3b-2a)
9a + 7b *remember to look and understand the letters!*
-58
8b
6a+7b
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
It is: 7b+4b-1b = 10b when simplified
7a plus 2b plus 3a plus 5b is equal to 10a plus 7b.
