What is the result when 1/8x - 2 5/7 is subtracted from 3 1/4x + 7 1/14
g100num [7]
Let's break it down:
We need an LCM, a least common multiple, so it's easier to subtract
3 1/4x + 7 1/14
-
1/8x - 2 5/7

3 1/4 is equivalent to 3 2/8     
2 5/7 is equivalent to 2 10/14

3 2/8x + 7 1/14        or you can break it down to two parts also
-                               3 2/8x - 1/8x = 2 1/8x
1/8x - 2 10/14          7 1/14 - (-2 10/14) = 9 11/14
------------------           - - = +
2 1/8x + 9 11/14

vichka [17]

Answer:

z = 1/9   and    z = 1

Step-by-step explanation:

-9 z^{2} + 10z - 1 = 0

You can check the answer using foil method

Then,

(-9z+1) = 0

-9z = -1

z = 1/9
