Question

10 th class linear equations​

Answer 1

Answer:

x=1/6    y=1/4

Step-by-step explanation:

Let 1/x=a and 1/y=b

Then, equations will be

a/2 - b = -1                   a + b/2 = 8  →(ii)

a - 2b = -2  →(i)

Subtract (i) from (ii)

b/2 + 2b=10

(b+4b)/2=10

5b=20

b=4

1/y=4

y=1/4

From (i)

a-8=-2

a=6

1/x=6

x=1/6
