दिया हुआ है:

दो संख्याओं का योग 90 है। 

एक संख्या दूसरी से 16 अधिक है। 

अवधारणा:

यहां हमें संख्या प्राप्त करने के लिए एक चर में समीकरण को बनाने की आवश्यकता है ताकि दूसरी संख्या निकाली जा सके।

हल:

माना कि दो संख्याएं x और x + 16 हैं।

प्रश्न के अनुसार,

x + x + 16 = 90

⇒ 2x = 74

⇒ x = 37 और x + 16 = 53

∴ दो संख्याएं 37 और 53 हैं।
