Step-by-step explanation:
=> 44 / x + y + 30 / x - y = 10 [ Equation 1]
=> 55 / x + y + 40 / x - y = 13 [ Equation 2]
Let ,
1 / x + y = u , 1 / x - y = v
44 u + 30 v = 10 [ Equation 3]
55u + 40 v = 13 [ Equation 4]
Multiply by 4 in equation 3 and 3 in equation 4 and divide
=> 176 u + 120 v = 40
=> 165 u + 120 v = 39
so,
u = 1/11 , 1 / x + y = u ,
Equation = x + y = 11
Putting the value of u in equation 2
v = 5
so,
Equation => x - y = 5
After solving this equation
x = 8
y = 3
