Question

which value for x makes the sentence true?

4x - 2 = 18

a. x = 24
b. x = 5
c. x = 20
d. x = 4

Explanation:

Step1: Add 2 to both sides

To isolate the term with \( x \), we add 2 to both sides of the equation \( 4x - 2 = 18 \). This gives us \( 4x - 2 + 2 = 18 + 2 \), which simplifies to \( 4x = 20 \).

Step2: Divide by 4

Next, we divide both sides of the equation \( 4x = 20 \) by 4 to solve for \( x \). So, \( \frac{4x}{4} = \frac{20}{4} \), which simplifies to \( x = 5 \).

Answer:

B. \( x = 5 \)
