Question

solve for x............................​

Answer 1

Solution

Given :-

• 1/x + 1/y = 6 -----------Equ(1)
• 1/y + 1/z = 7 ----------Equ(2)
• 1/z + 1/x = 5-----------Equ(3)

Find :-

• Value of x ,y % z

Explanation

Add equ(1) , equ(2) & equ(3)

we get , here

==> (1/x + 1/y) + (1/y + 1/z) + (1/z + 1/x) = 6 + 7 + 5

==> 2( 1/x + 1/y + 1/z) = 18

==> ( 1/x + 1/y + 1/z) =18/2

==> ( 1/x + 1/y + 1/z) = 9 -----------Equ(4)

First, Keep Value by equ(1) .

==> ( 6 + 1/z) = 9

==> 1/z = 9 - 6

==> 1/z = 3

==> z = 1/3

________________________

Second ,keep value by equ(2)

===> (1/x + 7 ) = 9

==> 1/x = 9 - 7

==> 1/x = 2

==> x = 1/2

________________________

Third , keep value by equ(3)

==> (1/y + 5) = 9

==> 1/y = 9 - 5

==> 1/y = 4

==> y = 1/4

________________________

Hence

• Value of x = 1/2
• Value of y = 1/4
• Value of z = 1/3

Ans.
