1. x = -7
2. x = 36
3. b = 55
4. y = -8
5. m = 9
6. x = 6
7.x = -7

9. b = 55
10. y = -8
11. m = 9
12. x = 7
13. y = 6
14. x = 5
15. not factorable
16. m < 6
17. a > 1
18. x < 5

is this your homework or something???

alright i will answer some of the questions as following:
1. -21 = 4x + 7 => -28=4x => x=-7
4. 3 - 2y = 19 => -2y=16 => y=-8
7. -21=4x+7 => -28=4x => x=-7
8. x/4 - 7 = 2 => x/4 = 9 => x = 36
10. -2y=16 => y=8
12. -20 = 5 ( 3 - x) => -20=15-5x => -35=-5x => x=7
16. m + 7 < 13 => m<6
17. a+4>5 => a>1

Looks like you should try testing your own skills. That's what homework is for.
You can obviously do this on your own it isn't hard. If you have trouble with one question put it up but don't put up a whole assignment.
Hell instead of writing it all out you would have been half done by now.
