solve  by elimination method

2} 3x+5y =7  &  11x=9+13y

  • 2
3x+5y=7
  • 0
x =1.444
.
y=50/94 or. 2.655
  • -1
3x+5y=7.....(i)
11x-13y=9....(ii)
MULTIPYING (i) BY 11 AND (ii) BY 3
 33x+55y= 77
 33x- 39y= 27
-     +         -    
94y=50
y=50/94
Substituting value in ....(i)
3x=7-(50/94)
3x=658-250 / 94
x=68/47
HENCE x=68/47 &  y=-13/5
