Answer:
-4y - 7
Step-by-step explanation:
-4y-4+(-3) what is my answer?
Here, you just find the like terms and combine them.
4 and -3 are like terms
So, we must combine them.
Remember that a positive plus a negative is the same thing as just subtracting.
-4 + -3 = -4 - 3
-4 - 3 = -7
-4y = -4y
So, our answer is -4y - 7
