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

Solution:

Linear equation can be written in different ways.

Any simple equation in x and y can be termed as a linear equation if it follows a certain set of rules.

For example, the highest (and the only) degree of both - x and y - variables in the equation should be 1. 

The problem statement can be translated into the mathematical equation as :

7/8  -  1/x  = 3/4

Now solve for x by isolating the variable x.

7/8 - 3/4 = 1/x

(7  - 6)/8  =  1/x

1/8  = 1/x

x =  8 

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

Summary:

Solving for x when  7 over 8 minus 1 over x equals 3 over 4, we get x = 8.
