What does x equal? explain how you got the answer.

x = -5

Step-by-step explanation:

so you need to get x by itself, so you will first subtract(8-8) and (-2 - 8). This will cancel out 8 and give you, 2x=-10. Then you will divide(2x÷2) and (-10÷2). This will cancel out the 2 and leave you with x=(-5)

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
