Question

1/2x+1/4x+1/8x=22 the value of X is?​

Answer 1

Answer:

1/2x+1/4x+1/8x=22

(4+2+1)8x=22

7/8x=22

7=22×8x

8x=7/22

x=7/8×22

x=7/176

hope it will help you.

Answer 2

Answer:

Polynomial = 1\2x + 1\4x +1\8x = 22

For finding the value of x we have to rationalise the denominators that is 2 , 4 and 8 . For that we have to find the LCM of the given denominators .                  

Given equation = 1\2x +1\4x + 1\8x = 22

LCM of 2 , 4 and 8 = 8

4\8x + 2\8x +1\8 = 22

7\8x = 22

7x = 22 X 8

x = 22 X 8 \7 = 176 \8

So , the required value of  is 176\8 . I am not going to factorise it more as if i do so i would get a very big answer as ...25.142857 bar
