Whats the value for n in 1/4+1/3n=1/2

First, we find the inverse operation.

1/4+1/3n = 1/2
-1/4          -1/4

1/2-1/4 = 2/4-1/4= 1/4 

Second, we re-write our equation.

1/3n= 1/4

Third, we do inverse operation of multiplication and apply it to both sides.

1/3n÷1/3= 1/4÷1/3

Divide 1/4 and 1/3

Keep the first fraction
1/4

Change the sign from division to multiplication.
1/4×

Flip the second fraction
1/4*3/1

Now multiply
1*3/4*1= 3/4

N= 3/4

Our final answer is that the value of n is 3/4
