Question

solve for z. z - 2 = 9 z = submit

Explanation:

Step1: Add 2 to both sides

To isolate \( z \), we add 2 to both sides of the equation \( z - 2 = 9 \). This gives us \( z - 2 + 2 = 9 + 2 \).

Step2: Simplify both sides

Simplifying the left side, \( z - 2 + 2 \) becomes \( z \). Simplifying the right side, \( 9 + 2 \) equals \( 11 \). So \( z = 11 \).

Answer:

11
