Question

1/x + 1/4=7/12
Solve for x

Answer 1

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.
