Answer 2

Answer:

Let 1/x = u and 1/y = v.

Hence, the equations become :

• 1/2 u - v + 1 = 0 .....Eq 1
• u + 1/2 v - 8 = 0 ......Eq 2

Now, let us solve them by substitution method.

From Equation 1,

➸ 1/2 u - v + 1 = 0

➸ 1/2 u = v - 1

➸ u = (v - 1)2

Substituting in equation 2,

➸ u + 1/2 v - 8 = 0

➸ (v - 1)2 + 1/2 v - 8 = 0

➸ 2v - 2 + 1/2 v = 8

➸ (4v + 1v)/2 = 10

➸ 5v = 10*2

➸ v = 20/5

➸ v = 4

Now, Finding u.

➸ u = (v - 1)2

➸ u = (4 - 1)2

➸ u = 3 * 2

➸ u = 6

Now, At last, Finding the values of x and y.

➸ 1/x = 6

➸ 1 = 6x

➸ x = 1/6

➸ 1/y = 4

➸ 1 = 4y

➸ y = 1/4

Hence, the values of x = 1/6 and y = 1/4.
