Question

If 37 x +41 = 70 and 41x +37y=36Then value of (x-y) is​

Answer 1

Step-by-step explanation:

37x + 41y = 70 ...(1)

41x + 37y = 86 ...(2)

Adding (1) and (2), we get,

78x + 78y = 156

x + y = 2 ...(3)

Subtracting (2) from (1), we get,

-4x + 4y = -16

y - x = -4 ...(4)

(3) + (4) gives 2y = -2 or y = -1

x = 3

Hence, x = 3 and y = -1
