Answer: x = 2 or x = -1
Step-by-step explanation: When you are solving an absolute value equation, you can split the problem up into two separate equations.
The first equation will look just like the original problem,
except for the absolute value signs (2x - 1 = 3).
The second equation will look just like the first,
but the right side will be changed to a negative (2x - 1 = -3).
Now solve each equation from here to get x = 2 or x = -1
