Question

Combine the like terms to create an equivalent expression:

y-(-3y)

I think this is the last one

LOL.......

Answer 1

Answer:4y
I got the same answer as the other person but here’s a explanation
Explanation: when subtracting something that’s already a negative it just adds instead, I’ve learned to think of it as looking like a giant plus mark “-(-“ so basically y+3y= 4y
