Solve : 2x + 7y = 11 5x + = 25

Question

KnowledgeBoat · Accepted Answer

2x + 7y = 11 ............... (1) 5x + = 25 ............... (2) Multiply 5 in the first equation and 2 in the second equation, then subtract both equations. (2x + 7y = 11) x 5 (5x + = 25) x 2 ⇒ 10x + 35y = 55 10x + 35y = 50 This means there is no pair of values for x and y that satisfies both equations. Hence, there is no solution for x and y.
