Question

what is the solution to this equation?
x - 13 = -4
a. x = -17
b. x = -9
c. x = 9
d. x = 17

Explanation:

Step1: Isolate the variable x

To solve for \( x \) in the equation \( x - 13 = -4 \), we need to isolate \( x \). We can do this by adding 13 to both sides of the equation.
\[
x - 13 + 13 = -4 + 13
\]

Step2: Simplify both sides

Simplifying the left side, \( -13 + 13 = 0 \), so we are left with \( x \). Simplifying the right side, \( -4 + 13 = 9 \). So we get:
\[
x = 9
\]

Answer:

C. \( x = 9 \)
