Let's take this phrase by phrase.

sum of three times a number and 8 = 3x + 8
Whenever there is a term mentioned without a definite value, we can represent it with a variable. In this case, I represented the number with "x".
is -22 means =-22
What equals -22? The sum of three times a number and 8 equals -22.
3x + 8 = -22
Subtract both sides by 8
3x = -30
x = -10

Final Answer: 1) -10

If you subtract 8 from -22 and then divide by 3 you get the answer, -10
