Well I got this: 2c+7=9+6-7c+2c 2c+7=15-9c 11c+7=15 (add 9c) 11c=8 ( Subtract 7) 11---11 ( Divide 11) C=0.72

It is an equation and the value of c is -7

-3.5. 2c would turn into -1.5 and seven wold turn to 3.5. add the two together and you get 2. 2+6=8 and you have your answer.

(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].

Without any information about a or b or c, all that can be said is: a + b + 2c = a + b + 2c Not particularly illuminating!

2c + 4 - 3c = -9 + c + 5 -c + 4 = c - 4 -2c = -8 2c = 8 c = 4

If 9 - 2c + 3 = -13, then c would be 12.5

(b + 2c)(b - c)

It is an equation and the value of c is -7

4 + 3c = 2c + 2Subtract 4 from each side:3c = 2c - 2Subtract 2c from each side:c = -2

2Ca + 3O2 + 2C -> 2CaCO3

It is 9

2c + 3 = 15 Subtract 3 from both sides: 2c = 12 Divide both sides by 2: c = 6

Y=15/(2c+2x)

-3.5. 2c would turn into -1.5 and seven wold turn to 3.5. add the two together and you get 2. 2+6=8 and you have your answer.
