|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."
