I have two basic formula where I need to remove the brackets and simplify. Can someone check my answers for me? I always seem to struggled when it comes to the add/subtract part, I get confused over which I should do.
1, 2(2x - y) - 3(x - 2y)
4x - 2y - 3x - 6y
x - 4y
2, x(2x - y) - y(x + 3y)
2x - xy - xy + 3y
2x - 2xy + 3y
I'm not sure about my solution to number 2.
Thanks
