Question

(v) 43x + 67y=-24
67x + 43y= 24​

Answer 1

Answer:

X=2.3,y=-1.181

Step-by-step explanation:

43x+67y=-24..... 1st

67x+43y=24 ........2nd

Multiply 1 st equation by 67 and 2 nd by 43 then we get,

2881x+4489y=-1608

2881x+1849y=1512

- - -

2640y=-3120

______________

Y=-1.181

Now we have to find out x then put this value of y in 1 st equation then we get,

43x+67(-1.181)=-24

43x-79.127=-24

43x=106

X=1.28
