Question

y + 11 = 987

Explanation:

Step1: Isolate the variable y

To solve for \( y \) in the equation \( y + 11 = 987 \), we need to subtract 11 from both sides of the equation. This is based on the addition property of equality, which states that if we subtract the same number from both sides of an equation, the equation remains balanced.
\[
y + 11 - 11 = 987 - 11
\]

Step2: Simplify both sides

Simplifying the left side, \( y + 11 - 11 \) simplifies to \( y \). Simplifying the right side, \( 987 - 11 = 976 \).
\[
y = 976
\]

Answer:

\( y = 976 \)
