Question

23x + 47y = 110 and 47x +23y =14 find x-y = .......​

Answer 1

Step-by-step explanation:

23x 29y=98 ) 29x23y =110(i) Adding i) and (ii) we get, 52x -52y =208 52(xy) = 208 x-y4 i) Substracting (i) fromi), -6x6y-12 x+y=2(iv) Now by solving (ii) and (iv), 2x =6 x =3 Substituting value of x in equation (iv),
