To solve the equations: 3x + 4Y = 115x − y = 3

To solve the equations: 3x + 4Y = 115x − y = 3

3x + 4Y = 11 & nbsp; ① 5x − y = 3 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; ② ① + ② × 4, we get 23x = 23, the solution is x = 1. Substituting x = 1 into ①, we get y = 2. So the solution of the system is x = 1y = 2
