Question

1. determine the solution of the equation |4x - 20| = 0

a. 0
b. 5
c. - 5
d. 5 and - 5

Explanation:

Step1: Recall absolute value property

The absolute value equation \(|A| = 0\) implies \(A = 0\). So for \(|4x - 20| = 0\), we set \(4x - 20 = 0\).

Step2: Solve for x

Add 20 to both sides: \(4x = 20\). Then divide both sides by 4: \(x = \frac{20}{4} = 5\).

Answer:

b. 5
