Wait so what is the point of this question?
A. -13 because if you remove the plus sign and replace it with the negative sign on the 3 you get -10-3
Answer:
6a-18
Step-by-step explanation:
Just slot the value of x (which is 20), everywhere you see the letter x.
Similarly, slot the value of y (which is 17), everywhere you see the letter y.
So forth,
x + 8 - y
becomes
20 + 8 - 17
which evaluates to 11.
