Question

solve.

-x + 5 = 18

select the correct choice below and, if necessary, fill in the answer box to complete your choice.

a. the solution is x = . (type an integer or a fraction.)
b. the solution is all real numbers.
c. there is no solution.

Explanation:

Step1: Subtract 5 from both sides

To isolate the term with \( x \), we subtract 5 from both sides of the equation \( -x + 5 = 18 \). This gives us \( -x + 5 - 5 = 18 - 5 \), which simplifies to \( -x = 13 \).

Step2: Multiply both sides by -1

To solve for \( x \), we multiply both sides of the equation \( -x = 13 \) by -1. This gives us \( (-1)(-x) = (-1)(13) \), which simplifies to \( x = -13 \).

Answer:

A. The solution is \( x = -13 \)
