Question 267909
The given equations are,
         5x+2y=18   ...(1)
         2x+3y=16   ...(2)
(1)*3=>  15x+6y = 54  ..(3)
(2)*2=>  4x+6y = 32  ...(4)
(3)-(4)=> 11x = 22
          x = 22/11
          x = 2
(1)=>     5*2+2y = 18
          10+2y = 18
          2y = 18-10
          2y = 8
          y = 8/2
          y = 4
The solution is x=2,y=4
