Question: Solve for x: 7 over 8 minus 1 over x equals 3 over 4.

First simplify the above equation by writing it numerically.

Answer: x = 8

7 over 8 minus 1 over x equals 3 over 4 written mathematically is 7/8 - 1/x = 3/4

Explanation:

Let's solve the equation

 7/8 - 3/4 = 1/x

(7 - 6)/8 = 1/x

1/8 = 1/x

x = 8

Hence for x: 7 over 8 minus 1 over x equals 3 over 4, x = 8
