Heyaa!

The answer is:-

(13x+11y=70)×13-----(a)

=169x+143y=51-----(1)

(11x+13y=74)×11

=121x+143y=814------(2)

Now,

Subtracting equation (1) from (2),

169x+143y=51

121x+143y=814

_. _. _

48x=763

x= 763/48

x=17.7

Now placing the value of x in eq.(a),

13(17.7)+11y=70

230.1+11y=70

11y=70-230.1

11y=160.1

y=14.5

Therefore, (x,y)=(17.7,14.5)
