The correct Answer is:
To solve the equation \( |2x + 3| + 5 = 0 \), we can follow these steps: ### Step 1: Analyze the equation The equation given is \( |2x + 3| + 5 = 0 \). ### Step 2: Isolate the absolute value To isolate the absolute value, we can subtract 5 from both sides: \[ |2x + 3| = -5 \] ### Step 3: Understand the properties of absolute values The absolute value function \( |a| \) is defined as always being non-negative, meaning \( |a| \geq 0 \) for any real number \( a \). Therefore, \( |2x + 3| \) must also be greater than or equal to 0. ### Step 4: Compare with the right side Since \( |2x + 3| \) is always non-negative, it can never equal a negative number. The right side of our equation is \(-5\), which is negative. ### Step 5: Conclusion Since there is no value of \( x \) that can satisfy the equation \( |2x + 3| = -5 \), we conclude that there is no solution to the original equation \( |2x + 3| + 5 = 0 \). ### Final Answer There is no value of \( x \) for which \( |2x + 3| + 5 = 0 \). ---
