solve each one if the following equation. Check your result in each case.
9)3x +7=9
10)5 -2x= -8
11)11- 3x =5
17)3x-4(2-5x)=7(x+5)-11
19)2y+5 by y+4 = 1
20)2x+1 by 3x - 2 = 5 by 9
21) 17(2 - x)-5(x +12) by 1 - 7x= 8
23)2y +11 by 4 = 1 by 3y +2
29) x+2 by 6 - {11 -x by 3 - 1 by 4} =3x-4 by 12
30)3 by 4(7x-1)-{2x - 1-x by 2} = x + 3 by 2
31) 0.3x + 0.4=0.28x + 1.16
32)0.18(5x-4)=0.5 + 0.8

Answer:
9) 3x = 9-7
3x = 2
x = 2/3
10)5-2x=-8
- 2x = -5-8
-2x = -13
x = -13 +2
x = -11
11)11-3x=5
-3x =5-11
-3x =-6
x = -6+3
x = -3
sorry i do all but these are correct
