Simplify 8a − 2a.(1 point)

6a

Simplify 12e − 5f − 7e +3f

To simplify the expression 8a - 2a, you need to combine like terms. Like terms are terms that have the same variable(s) with the same exponent(s). In this expression, we have two terms with the same variable "a" raised to the power of 1.

To simplify, we add or subtract the coefficients (the numbers in front of the variable) and keep the variable unchanged.

In this case, the coefficient of the first term is 8, and the coefficient of the second term is -2. Adding these coefficients gives us 8 - 2, which equals 6.

So, the simplified expression is 6a.
