Question

1. krystal says that you need to add to solve the subtraction equation $y - 11 = 52$. is krystal correct? explain.

Explanation:

Step1: Isolate the variable $y$

To solve $y - 11 = 52$, we use inverse operations. The inverse of subtraction is addition. Add 11 to both sides of the equation to cancel out the $-11$ on the left.
$$y - 11 + 11 = 52 + 11$$

Step2: Simplify both sides

The left side simplifies to $y$, and the right side is the sum of 52 and 11.
$$y = 63$$

Step3: Verify Krystal's claim

Krystal states you need to add to solve the equation, which matches the inverse operation we used (adding 11 to both sides) to isolate $y$.

Answer:

Yes, Krystal is correct. To solve $y - 11 = 52$, you use the inverse operation of subtraction, which is addition: adding 11 to both sides isolates $y$, giving $y = 63$.
