4x +2y= 13

Ans:12x +3y=23

Answer 2

Answer:

Step-by-step explanation: (8x + y = 10)2 (to make value of y same as eqn 2)

                                             4x+2y=13

16x+2y=20        for y put value of x in eqn 1 or 2

4x+2y =13          hence  4(7/12)+2y=13

-      -      -            35/12+2y =13

----------------         (35+24y)/12=13

12x      =7            35+24y=156

x=7/12                 24y=156-35

                           y=121/24=5.04
