It is: 19b+7b = 26b
It is: 7b+10 simplified
(-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
10a+7b undefined variables cannot be determined
4b plus 7b plus 5 will equal 11b plus 5. When you have two variables that are the same you can add the two numbers with the variables remaining the same.
