Question

1. 3 = z - 11

Explanation:

Step1: Add 11 to both sides

To solve for \( z \), we add 11 to both sides of the equation \( 3 = z - 11 \). This gives us \( 3 + 11 = z - 11 + 11 \).

Step2: Simplify both sides

Simplifying the left side: \( 3 + 11 = 14 \). Simplifying the right side: \( z - 11 + 11 = z \) (since \(-11 + 11 = 0\)). So we have \( z = 14 \).

Answer:

\( z = 14 \)
