Answer
$x+3=5$
Work Step by Step
Each side of the diagram represents one side of the equation. The bar separating the two sides represents the equal sign.
The left side includes a green tile. The green tile represents a variable such as x.
The left side also includes 3 yellow tiles. Each yellow tile represents +1, so 3 yellow tiles is +3.
The right side contains 5 yellow tiles, so it represents +5.
Combine the parts into an equation.
$x+3=5$
