Final answer:
To solve the equation 9 + x = 6, subtract 9 from both sides to isolate x and find x = -3.
Explanation:
To solve the equation 9 + x = 6, we want to isolate the variable x on one side of the equation. Since 9 is being added to x, we can subtract 9 from both sides of the equation to remove it. This leaves us with x = 6 - 9, which simplifies to x = -3.
