Question 713529
 given equations 
 2x+5y=2
3x-5y=53
 add both the equations
  2 x + 5y +3x  -5y  = 2+53
            5x  = 55
    divide with 5 on both sides
   5x/5  = 55/5
                 x = 11
 put x= 11 in  2x +5y  =2
                2(11)+ 5y  = 2
                22  + 5 y  = 2
                       subtract 22 on both sides
                       22+ 5y-22  = 2-22
                           5 y  =-20
                         divide with 5 on both sides
                                 5y /5  = -20/5
                                     y= -4
  x = 11  & y =-4
