Question

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

Answer 1

Given equation is

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

We can solve it by subtracting 1/4 both side

`(1)/(x) + (1)/(4) - (1)/(4) = (7)/(12) - (1)/(4)`


`(1)/(x) = (7)/(12) - (1)/(4)`

`= (7 - 3)/(12)`

`= (4)/(12)`

`= (1)/(3)`

So
`(1)/(x) = (1)/(3)`
On comparing x = 3.

SO the solution of equation is x = 3
