💡 Analysis & Explanation
Mathematical Balancing
The objective is to substitute the operators to satisfy the target equation exactly.
Evaluating Option D
Applying the sequence 'x, +, -' gives the formal mathematical expression 27 * 3 + 19 - 10.
BODMAS Execution
First, perform multiplication: 27 * 3 = 81. Next, perform addition: 81 + 19 = 100. Finally, perform subtraction: 100 - 10 = 90. This perfectly balances both sides of the equation.
Conclusion
The symbol set 'x, +, -' is definitively mathematically correct.
