解题---Extraction Content: **Title:** 相同图形填入相同的数 (Fill in the same number for the same shape) **Problem Description:** The problem presents a system of two equations represented using geometric shapes. Equation 1: Square + Circle = 15 Equation 2: Square × 5 + Circle × 3 = 57 **Equations:** Equation 1: □ + ○ = 15 Equation 2: □ × 5 + ○ × 3 = 57 **Chart/Diagram Description:** * **Type:** Mathematical equations using geometric shapes as placeholders for numbers. * **Main Elements:** * A blue square symbol (□) representing an unknown number. * A yellow circle symbol (○) representing another unknown number. * Mathematical operators: addition (+), multiplication (×), equals (=). * Numbers: 15, 5, 3, 57. * The equations are arranged vertically. * The second equation highlights the terms with dashed boxes around the shape and its coefficient (blue dashed box around □ × 5, yellow dashed box around ○ × 3).
