Answer:
Step-by-step explanation:
Two numbers are given. -7 and 3. What are happening with the numbers? well, the question STARTS with -7 points then he gains 3. Well what happens if you had 0 points and gained 3? you'd add them. So the same thing happens here. so the expression is -7+3 = -4
In a proper sentence the answer woud be something like "The final score is -4 since he gained three after having -7."
Let me know if there was something you didn't understand.

x and y have the same exponent; So, they can be expressed as:
|x| meaning how much is from x to 0 so for example |4| = 4 and |-10| = 10 ( it could never be a negative) but when the - is on the outside of the two lines then it turns to a negative like for example:
|23|= 23
But then…
-|23|=-23
^because anything that is out of the two lines doesn't mean distance from that number to 0 only the ones inside
