Answer:
The solutions the equation 1 are -1.3 and 2. The solutions to equation 2 are -1 and 0.
Step-by-step explanation:
Isolate the absolute value for equation 1. Then, set two equations equal to 5 and -5.
3x - 1 = 5 and 3x - 1 = -5
Solve for x in both and you would get -1.3 and 2.
Do the same for equation 2.
2x + 1 = -1 and 2x + 1 = 1
Solve for x and you would get -1 and 0.
