2(x-y)-(x+y)
I have been stuck on this problem for ages.. Please help!!
2(x-y)-(x+y)
2x - 2y - x - y = x - y
Oh!! Sorry; forgot to say what the objective is.. I'm supposed to simplify, but I'm not sure how to distribute the two and everything..
I still don't really understand.. Sorry....
Distribute over everything in the parentheses.
2(x - y) = 2x - 2y
-(x + y) = -x + -y = -x - y
2x - x - 2y - y = x - 3y
I still don't really understand.. Sorry....
Scratch that, I understand. Thank you!
To solve the expression 2(x-y)-(x+y), we need to simplify it by applying the rules of arithmetic.
1. Start by distributing the 2 to the terms inside the parentheses:
2(x) - 2(y) - (x + y)
2. Simplify each term:
2x - 2y - x - y
3. Combine like terms:
(2x - x) + (-2y - y)
x - 3y - y
4. Further simplify:
x - 4y
So, the simplified expression for 2(x-y)-(x+y) is x - 4y.
