What is the solution to x + 5 = -3?

What is the solution to x + 5 = -3?

• A. -6
• B. -8
• C. -8.0
• D. -7

Answer: (C)

To solve the equation x + 5 = -3, the goal is to isolate the variable x. The first step is to eliminate the constant on the left side of the equation. This can be accomplished by subtracting 5 from both sides: x + 5 - 5 = -3 - 5 This simplifies to: x = -3 - 5 Calculating the right side gives: x = -8 Thus, the solution is x = -8. Since option C presents -8 as an answer and also denotes it with a decimal format (-8.0), it reflects the same numerical value. Both representations are considered equivalent in mathematics. This is why choosing -8, whether written as an integer or as -8.0 in decimal form, confirms that it aligns with the correct solution to the equation.
