27 = 12c - 5(6 - 2c) solve for c

Answer:
c = 35
Step-by-step explanation:
27 = 12c - 5(6 - 2c)
27 = 12c - 30 + 10c
27 + 30 = 12c + 10c
57 = 22c
57 - 22 = c
35 = c
27 = 12c - 5(6 - 2c)
First I’m just going to flip the equation around to make it easier to read:
12c - 5(6 - 2c) = 27
Next we will multiply everything in the brackets by what is on the outside of the brackets (remember a negative times a negative is a positive):
12c - 30 + 10c = 27
Now I’m going to add the like terms (things that have the same letter):
22c - 30 = 27
Now lets isolate 22c by adding 30 to both sides:
22c = 57
Now divide both sides by 22 to get the value of c:
c = 2.59

= 120 2/3 + 13 2/5
= (120+13) (2/3 + 2/5)
= 133 + (10/15 + 6/15)
= 133 + 16/15
= 133 + 1 1/15
= 134 1/15
