Simplify 2 (x - 4) + 7 (x + 2).

9x - 6

9x - 4

9x + 6

With this question you will distribute and add. You want to do this from left to right.

2*x = 2x

2*-4 = - 8

Now the equation is (2x-8) + 7 (x+2). This is where you distribute again.

7*x = 7x

7*2 = 14

The equation is now (2x-8) + (7x+14) which can also be rewritten to be 2x - 8 + 7x + 14. Here you combine like terms through adding.

2x + 7x = 9x

14 - 8 = 6

Remember to always keep the sign of the number when adding. This means your answer would be 9x+6 or 6+9x.

2 (x - 4) + 7 (x + 2)

= 2x - 8 + 7x + 14

= 9x + 6

answer

9x + 6
