Step-by-step explanation:
First, you would follow PEMDAS, so the parenthasis are first. Since you can't subtract 2x and 8, you would distribute to 5. This would make the problem 10x-45+-15. They you would add 45, so that the problem would become 10x=30. Finally, you would divide the entire problem by 10 so that you isolate the variable x=3

Answer:
62, 64, 66
Step-by-step explanation:
I like to work "consecutive integer" problems by considering the average, or middle value. If we call that x, then the problem statement tells us ...
(x -2) +(x +2) = 128
2x = 128 . . . . . collect terms
x = 64 . . . . . . . divide by 2
The middle integer is 64, so the three even integers are 62, 64, 66.
