माना एक कुर्सी का मूल्य = ₹ x

तथा एक मेज का मूल्य = ₹y

प्रश्नानुसार,

पहली शर्त, 4x + 3y = 2100 ………(1)

तथा दूसरी शर्त, 5x + 2y = 1750 …..(2)

समी० (1) को 2 से तथा समी० (2) को 3 से गुणा करने पर,

x का मान समी० (1) में रखने पर,

4 × 150 + 3y = 2100

600 + 3y = 2100

3y = 2100 – 600 = 1500

y = \(\frac{1500}{3}\) = 500

अतः एक कुर्सी का मूल्य = ₹ 150 और एक मेज का मूल्य = ₹ 500
