combine like terms on each side of the equation. for example, write 3 instead of 1 + 1 + 1.

Explanation:

Step1: Count tiles on left side

Left side: 1 green tile (\(x\)) and 9 yellow tiles (each 1), so \(x + 9\).

Step2: Count tiles on right side

Right side: 12 yellow tiles (each 1), so \(12\).

Step3: Form equation

Combine to get \(x + 9 = 12\).

Answer:

\(x + 9 = 12\)
