Data:x + 2y = 30 (1)Find\((\frac{2y}{5} + \frac{x}{3}) +(\frac{x}{5} + \frac{2y}{3})\)Calculation:Let y = 0 and x = 30Since it satisfies equation (1)Hence\((\frac{2y}{5} + \frac{x}{3}) +(\frac{x}{5} + \frac{2y}{3})\)\(= (\frac{2\times 0}{5} + \frac{30}{3}) +(\frac{30}{5} + \frac{2\times 0}{3})\)= 0 + 10 + 6 + 0 = 16. If x + 2y = 30, then \((\frac{2y}{5} + \frac{x}{3}) +(\frac{x}{5} + \frac{2y}{3})\) will be equal is 16
