Problema Solution
Twice the larger of two numbers is three more than five times the smaller, and the sum of four times the larger and three times the smaller is 71. What are the numbers?
Answer provided by our tutors
LET X AND Y BE NUMBERS
SO 2X = 5Y+3 OR 2X- 5Y = 3
4X+3Y = 71
MULTIPLYING EQN 1 BY 3 , EQN 2 BY 5 WE GET
6X-15Y = 9
20X + 15Y = 355
OR 26X = 364
SO X = 14
SO Y = 28 -5 / 5 = 5
SO 14 , 5
