Answer 1

To solve the equation \(31 - 9x = 4\), we first isolate \(x\).

1. Subtract 31 from both sides: \[ -9x = 4 - 31 \] \[ -9x = -27 \]

2. Divide both sides by -9: \[ x = \frac{-27}{-9} \] \[ x = 3 \]

The solution set containing this single solution can be expressed in set notation as: \[ { 3 } \]

So the correct answer to the question is \({ 3 }\).
