To solve the equation \( \sqrt{3x^2 - 10} + 7 = 4 \), we first isolate the square root term.
- Subtract 7 from both sides: \[ \sqrt{3x^2 - 10} = 4 - 7 \] \[ \sqrt{3x^2 - 10} = -3 \]
Since the left side of the equation (the square root) must be non-negative, and the right side is negative, there are no solutions to this equation.
Thus, the conclusion is that there are no valid values for \( x \) that satisfy the given equation. The answer is:
\( x = \) (no solution)
