wrong -- the set is {3}
You are correct, I apologize for the mistake. The correct set notation for the solution set to the equation 31 - 9x = 4 is {3}.
{x=3}
left brace x equals 3 right brace
The set notation that correctly expresses the solution set to the equation 31 - 9x = 4 is:
{x = 3} (left brace x equals 3 right brace)
Explanation of how to get the answer:
1. Start with the equation 31 - 9x = 4.
2. Simplify the equation by subtracting 31 from both sides: -9x = -27.
3. Divide both sides of the equation by -9 to solve for x: x = 3.
4. The solution to the equation is x = 3.
5. Express the solution set using set notation, where the variable x is equal to 3: {x = 3}.
