Solve and and check the equation, buit only type your answer as variable=solution.

1. 5c + 6 - c = 2c + 9 -c
2. 6d +1 - 2d = 3d - 3
3. 4d + 3d + d = 3d - 15
4. 15B - 6 = 8B - 3B + 14
5. 7h + h - 6 = 10 + 4h


JUST IN CASE U DIDNT KNOW IM NOT IN SCHOOL TODAY, THERE IS A TEACHERS CONVENTION. THIS WOULD REALLY HELP ME GET CAUGHT UP IN SCHOOL. IF U KNOW HOW TO DO IT , THEN LEAVE UR EMAIL ADDRESS SO I CAN ASK U FOR MORE PLEASE. IF U DONT WANT TO LEAVE IT THEN FINE BE LIKE THAT.

1. 5c + 6 - c = 2c + 9 - c
5c - c - 2c + 2 = 9 - 6
3c = 3
c = 1

2. 6d + 1 - 2d = 3d - 3
6d - 2d - 3d = -3 - 1
d = -4

3. 4d + 3d + d = 3d - 15
8d - 3d = -15
5d = -15
d = -3

4. 15B - 6 = 8B - 3B + 14
15B - 8B + 3B = 14 + 6
4B = 20
B = 5

5. 7h + h - 6 =10 + 4h
8h - 4h = 10 + 6
4h = 16
h = 4


Done.

1. 5c + 6 - c = 2c + 9 - c
4c - c = 9 - 6
3c = 3
c = 1

2. 6d + 1 -2d = 3d - 3
4d - 3d = -4
d = -4

3. 4d + 3d + d = 3d - 15
5d = -15
d = -3

4. 15B - 6 = 8B - 3B +14
15B - 5B = 20
10B = 20
B = 2

5. 7h + h -6 = 10+4h
8h - 4h = 16
4h = 16
h = 4

and u can mail me of ur problem to pavan_coolj@yahoo.co.in

1. 5c + 6 - c = 2c + 9 -c
4c+6=c+9
3c=3
c=1

2. 6d +1 - 2d = 3d - 3
4d+1=3d-3
d=-3-1=-4

3. 4d + 3d + d = 3d - 15
8d=3d-15
5d=-15
d=-3

4. 15B - 6 = 8B - 3B + 14
15b-6=5b+14
10b=20
b=2


5. 7h + h - 6 = 10 + 4h
8h-6=10+4h
4h=16
h=4

1. C=1
5*1+6-1=2*1+9-1
5+6-1=2+9-1
10=10

Sry, I'm at work but I'm still working on the rest.
