HI GUYS,

NOW FOCUS ON ANSWER..
Step-by-step explanation:
x + 1/y = 1 ——1
y + 1/z = 1 ——2
By using equation 1 and 2, substitute equation 2 into 1 by making y the subject of equation 2.
y = 1 - 1/z
Now with the value of y from equation 2, by substituting into equation 1, it allows you to have x and z together.
x + 1/(1 - 1/z) = 1
Multiply the entire equation by (1 - 1/z)
x -x/2 + 1 = 1 - 1/z
Bring the terms x and 1/z as per requested from the question together, then the other terms to the other side
x + 1/z = x/z
