Question

1. what value of x satisfies the equation?

9x - 7 = 13
a. 29
b. 20
c. \\(\frac{20}{9}\\)
d. \\(\frac{13}{7}\\)

Explanation:

Step1: Add 7 to both sides

To isolate the term with \( x \), we add 7 to both sides of the equation \( 9x - 7 = 13 \). This gives us \( 9x - 7 + 7 = 13 + 7 \), which simplifies to \( 9x = 20 \).

Step2: Divide by 9

Next, we divide both sides of the equation \( 9x = 20 \) by 9 to solve for \( x \). So, \( x=\frac{20}{9} \).

Answer:

C. \(\frac{20}{9}\)
