Answer 2

8

Explanation:

First, you want to substitute your a, b, c, and d, which you would get 3(2) + 3(8) divided by sign 2 - 2(5). According to PEMDAS, we will multiply our numbers in the parenthesis with the outside number next to it, so you should have gotten 6 + 24 divided by sign 2 - 10. Next, you will divided 24 by 2 to get 12, so the equation will now look like 6 + 12 - 10. Finally, just work it out 6 + 12 is 18 minus 10, is 8. I hope this helps :)
