Question

Simplify the following expression by combining like terms. Select the most simplified expression: 3y+y+2y−4y

Answer 1

Answer: 2y

Explanation: put a one in front of the y since it has no coefficient then collect like terms: (3+1+2-4)y. 3+1=4-4=0 therefore the only one left is 2 giving you 2y.

I hope that helps! Have a good day :)
