how to find x and y
Asked by sujatanallana123456 | 20 Jun, 2020, 04:35: PM
73x + 27y = 19     ....(1)
27x + 73y = -119  ....(2)

Adding (1) and (2), we get

100x + 100y = -100
→ x + y = -1    ... (3)

Subtracting (1) from (2), we get

-46x + 46y = -138
→ x - y = 3      ... (4)

Adding (3) and (4), we get

2x = 2 → x = 1
From (1)
y = -1 - 1 = -2
