Add or subtract the following (this is algebra for those people who don't know):
1. 4x + 3xy+ -5x = ?

2. 6x + 2y + 5x + -3y = ?

3. 2m + -8m + -4m + -6m = ?

4. -18xy + 9x2y + 4xy + -5x2y = ? (note:the 2 in this number are exponents)

5. a + 2b + 3c + d + 2a + -b + -c + d

Please answer it now im going to need it tommorow (i use Philippine Time)

1) 4x - 5x + 3xy = -x + 3xy
2) 6x + 5x + 2y - 3y = 11x - y 3) 2m + (-8m - 4m - 6m) = 2m -18m = - 16m
4) 9x^2y - 5x^2y - 18xy + 4xy = 4x^2y - 14xy
5) a + 2a + 2b - b + 3c - c + d + d = 3a -b + 2c + 2d.

Number 5 is not correct :-)
2b - b = +b right? ?
All your answers are correct :-) I looked at b's it again. I had to zoom in. You're right :-)
