First, disregard the sign for absolute value and solve for x.
2x - 1 = 3x + 5 2x - 3x = 5 + 1 -x = 6 x = -6
Now, you have to interpret the absolute value. The absolute value of x is always the positive version of whatever the number is. Since x = -6, its absolute value is 6. Therefore, the possible value for x is only one, which is 6.
