Question

|2c+8|=|10c| Please help explain it too, if you can! :)

Answer 1

|2c+8|=|10c|

You will need these 2 equations:

2c + 8 = 10c      2c + 8 = -10c

Solve each for an answer:

2c + 8 = 10c

8 = 8 c

c = 1

2c + 8 = -10c

8 = -12c

c= -8/12 or -2/3

So... C = 1 or -2/3

You have to solve this both ways because the value inside the absolute sign can be either a negative or positive answer and still be "absolute."
