Question

solve:
57x + 53y = 163 and 53x + 57y = 110​

Answer 1

Step-by-step explanation:

57x+53y=163......................1)

53x+57y=110......................2)

In equation 1

x=(163-53)/57.......................3)

Put the value of x in equation 2

53[(163-53y)57]+57y=110

(8639-2886)/57+57y=110

(5830+3249y)/57=110

5830+3249y=6270

3249y=440

y=0.13

Put equation 3

x=(163+53×0.13)/57

X=(163+53.13)/57

X=216.13/57

X=3.791
