Solve the following equation for x.
|12x - 3| = 1

Question

Quizplus · Accepted Answer

When solving an equation with one variable, your goal is to isolate the variable on one side of the equal sign. You do this by moving all of the other numbers to the opposite of the equal sign. You move numbers by performing the opposite operation (subtraction/addition and multiplication/division), on both sides of the equation to keep it balanced. 
|12x - 3| = 1
In this equation, we see the use of the absolute value symbol, |    |.
The absolute value of a number is the magnitude of that number. In other words, it is the number of places it is from zero. This means that the absolute value of a negative number is simply the number of spaces it is away from zero (in either direction). For example, |- 3| = 3 because -3 is three places from zero.
When there is an absolute value within an equation, it represents the absolute value of that number, when x is known. When we see the absolute value symbol, it alerts us that the value of the number inside can be either positive or negative.
Therefore, we must solve for both possibilities, and separate the problem into the positive answer and the negative answer and solve for both:
