To find the equation that matches the solution set of {5}, we need to evaluate each given equation for the possibility of having only the solution \(x = 5\).
-
Equation: \(x^2 - 10 = 15\)
Rearranging gives:
\(x^2 = 25\)
\(x = 5\) or \(x = -5\)
Solution set: {5, -5} (does not match) -
Equation: \(2x - 20 = 30\)
Rearranging gives:
\(2x = 50\)
\(x = 25\)
Solution set: {25} (does not match) -
Equation: \(x + x - 9 = 1 + x\)
Simplifying gives:
\(2x - 9 = 1 + x\)
\(2x - x = 10\)
\(x = 10\)
Solution set: {10} (does not match) -
Equation: \(3x + 4 = 7\)
Rearranging gives:
\(3x = 3\)
\(x = 1\)
Solution set: {1} (does not match)
None of the provided equations have a solution set that matches {5}. Therefore, please verify if all options were listed, or if there might be a mistake somewhere in the problem setup.
