Question

Solve for x: 7/8-1/x=3/4

Answer 1

7/8-1/x=3/4
subtract 3/4 and 7/8
then get x=8

Answer 2

7/8 - 1/x = 34

Rewrite 3/4 to have a common denominator as 7/8:

3/4 x 2 = 6/8

Now you have 7/8 - 1/x = 6/8

The fraction being subtracted would also have a common denominator, so x would be 8.

x = 8
