Q12 Which set notation correctly expresses the solution set to the equation 2x – 8 = 10?

Question

(x=9)
{9}
(9)
{x=9}

Answer 1

The correct set notation to express the solution set to the equation \(2x - 8 = 10\) is \({9}\).

When you solve the equation, you find that \(x = 9\). The solution set, which contains this single solution, is represented with curly braces as \({9}\).

So the answer is \({9}\).
