- Anonymous1 decade agoFavorite Answer
(12C + 35) - (5C - 11) = -2
12C + 35 - (5C - 11) = -2 >>>Remove parenthesis around
12C + 35 - 5C + 11 = -2
12C - 5C = -2 - 35 - 11>>>Combine like term and must bring unknown C to the left.
7C = -48
C = -48 / 7
C = -6.86 >>>2 decimal places

(12C + 35) - (5C - 11) = -2
First, distribute the negative sign through the second parentheses:
12C + 35 - (5C) - (-11) = -2
12C + 35 - 5C + 11 = -2
Combine like terms:
(12C - 5C) + (35 + 11) = -2
7C + 46 = -2
Get 7C alone:
7C + 46 - 46 = -2 - 46
7C = -48
Get C alone:
7C / 7 = -48 / 7
C = -48 / 7

(12C + 35) - (5C - 11)= -2
12C +35 -5C +11= -2
7C= -2 -35 -11= -48
C= -48/7= -6.857143

(12C+35)-(5C-11)= -2
==] 12C+35-5C+11= -2
==] 7C+46= -2
==] 7C= -2-46
==] 7C= -48
==] C= (-48/7)

12C - 5C + 35 + 11 = -2
7C = -2 - 35 - 11
C = -48/7
C = -6.857
Let X be (12C +35) - (5C -11)
X = [12(-6.857) +35] - [5(-6.857)-11]
X = - 47.284 - (-45.284)
X = -2

(12C+35)-(5C-11)=-2
12C+35-5C+11=-2
7C=-35-11-2
7C=-48
c=-48/7
