To solve the equation |4x - 1| = 7, we will break it down into two cases based on the properties of absolute value.
Step 1: Set Up Cases for Absolute Value
The equation |4x - 1| = 7 gives us two cases to consider:
1.Case 1:
4x - 1 = 7
2.Case 2:
4x - 1 = -7
Step 2: Solve Each Case
For Case 1:
4x - 1 = 7
Add 1 to both sides:
4x = 7 + 1
4x = 8
Now, divide by 4:
x = 2
For Case 2:
4x - 1 = -7
Add 1 to both sides:
4x = -7 + 1
4x = -6
Now, divide by 4:
