Question

c) $-x + 4 = -9$

Explanation:

Step1: Subtract 4 from both sides

To isolate the term with \( x \), we subtract 4 from both sides of the equation \(-x + 4 = -9\). This gives us \(-x + 4 - 4 = -9 - 4\). Simplifying both sides, we have \(-x = -13\).

Step2: Multiply both sides by -1

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

Answer:

\( x = 13 \)
