To simplify the expression 7a - 6, we combine like terms by adding or subtracting coefficients of terms with the same variables. In this case, there are no like terms to combine, so the expression remains as 7a - 6. It cannot be simplified further without additional context or information.
It looks like you've taken 'a' away from '7a' three times, so you probably have 4 of them left.
-2ab
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
9a + 1
