Answer 1

Answer:

x = -1

Step-by-step explanation:

5/7(1/x) + 3/14 =7/2(1/x) + 3

Let 1/x = y

5/7(y) + 3/14 = 7/2(y) + 3

5y/7 + 3/14 = 7y/2 +3

5y/7 - 7y/2 = 3 - 3/14

(10y - 49y)/14 = (42 - 3)/14

-39y/14 = 39/14

-39y = 39

y = 39 /-39

y = -1

Since 1/x = y

1/x = -1

1 = -x

x = -1

Now check by putting the value in equation :-

-5/7 + 3/14 = -7/2 + 3

(-10 + 3)/14 = (-7 + 6)/2

-7/14 = -1/2

-1/2 = -1/2

Hence checked the answer is correct
