Which set notation correctly expresses the solution set to the equation 31−9x=4 ?(1 point)

1 answer

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 \({ 3 }\).
