Mathematics - 20 June 2007

Hi! I'm 2nd Year High School from the Philippines and I got problems on Solution Set! Give me the answers and tell me or explain to me how you got it step by step! Thanks alot ><
1.) 8y - 35 = 3y
2.) 6x + 3 = 2x + 11
3.) 5y - 2 = 28 - y
4.) -18s + 6s + 2s = -9s + 15
5.) 7(2a - 1) = 21
6.) 9 = 3 (5x - 2)
7.) 2(3 + 4m) - 9 = 45
8.) -2 (r - 1) + 7 = 3 (r + 5)
9.) 7 - 2x - ( - x + 7 ) = 3 + x - (x - 3)
10.) z - 6 (3z + 4) = 5[2z + (3z + 4) - 22]

Once again! Thanks alot!
