Answer:

The value of x is 3.

Explanation:

When solving for a variable you must isolate the variable.


(1)/(x) +(1)/(4) =(7)/(12)
Find and multiply the equation by the LCM:

(1)/(x) +(1)/(4) =(7)/(12)=12+3x=7x

=12+3x=7x
Move 7x to the left side of the equation:

3x-7x=-4x

-4x=-12
Divide -4 on both sides:

-4x/-4=x

-12/-4=3

x=3

I hope this helps you.
