2 మిక్సర్లు + 1 టీవీ = రూ. 700
2 టీవీలు + 1 మిక్సర్ = రూ. 980
భావన:
సమీకరణాల వ్యవస్థను ఉపయోగించి ఈ సమస్యను పరిష్కరించవచ్చు.
పరిష్కారం:
2M + T = 700
2T + M = 980
రెండు సమీకరణాలను జోడించండి:
2T + M + (2M + T) = 980 + 700 ⇒ T + M = 1680/3 = 560
2T + M = 980
T + T + M = 980
T + 560 = 980
T = 420
కాబట్టి, ఒక టీవీ విలువ రూ. 420.
