Question

Evaluate the expression when a = 2 and x = - 6
6a -x

Answer 1

18

Explanation:

6(2) - (-6)

12 +6

18

Answer 2

To solve this, we can substitute 2 in for the variable “a” and -6 in for the variable “x.”

6a - x = 6(2) - (-6)

6a - x = 12 - (-6)

6a - x = 18

When evaluating the expression when a = 2 and x = -6, we will find that our answer is 18.
