Mr.Napoli, I didn't know we had the homework on page 132, but i will post that one, instead of the worksheet.
pg 132
4)9x+44-2
+2x +2
11x=44
x=4
6)y=4y+30
+y 3y+30
3y=30
y=10
14)5c=2c-81
-2c
3c=-81
c=-27 ??
16)0.5m-30=1.1m
-0.5 -0.5
-30=0.6m
m=-50 ??
18)7r+10=3r+50
-3r
4r+10=50
-10 40
r=10
24)c+20=55-4c
-c -1c
-35=-5c
c=7
28)i don't really understand this, but this is what i got
28)x-3(1-x)=47-x
x-3+3x=47-x
x+3x-3=47-x
4x-3=47-x
5x-3=47+x
x=10
38)6x=3x+24
3x=24
x=8
Thankyou, Fathia

4. Plus 2x on both sides, then divided by 11 on both sides. x=4
6. Minus y on both sides, then minus 3y on both sides, and then divided -3 on both sides. y=-10.
10. Plus 2y on both sides, then divided by 10 on both sides. y=9
14. Minus 2c on both sides, then divided by 3 on both sides. c=-27
16. Minus 0.5m on both sides, then divided by 0.6 on both sides. m=-50
18. Minus 3r on both sides, then minus 10 on both sides, and then divided by 4 on both sides. r=10
24. Plus 4c on both sides, then minus 20 on both sides, and then divided by 5 on both sides. c=7
16. Minus 7y on both sides, then minus 29 on both sides, and then divided by 2 on both sides. y=-17
