1) 5y + 4 = 4y + 5
11a + 9 = 4a + 30
2w + 3 = 4w  5
2) 3a  10 = 4 + a
2x  1 = x  3
6n + 4 = n  11
3) 29r + 4 = 28 + 13r
7x  11 = 19 + 3x
4) b + 3 = 2b  7
I'm having a bit trouble and really confused with the problems. I'm NOT asking you to do this homework for me because that would wrong and I won't learn anything. Can you do #1, 2, 3, and 4 for me for I can do the problems below it since it's similar to them.

1)
5y + 4 = 4y + 5
5y  4y = 5  4
y = 1
2)
3a  10 = 4 + a
3a  a = 4 + 10
2a = 14
a = 2
3)
29r + 4 = 28 + 13r
29r  13r = 28  4
16r = 24
r = 24/16 = 1 8/16 = 1 1/2 
thanks
2w + 3 = 4w  5
4w  2w = 3 + 5
2w = 8/2
w = 4
am i correct???? 
You're welcome.
Your answer is correct. 
2x  x = 3  1
1x = 2/1
x = 2 
Yes.
