Multiply both sides by 12
4n%2B3n=6
Take it from there and solve for n.

n%2F3%2Bn%2F4=1%2F2 Start with the given equation.


12%28n%2Fcross%283%29%2Bn%2Fcross%284%29%29=12%281%2Fcross%282%29%29 Multiply both sides by the LCD 12 to clear any fractions.


4n%2B3n=6 Distribute and multiply.


7n=6 Combine like terms on the left side.


n=%286%29%2F%287%29 Divide both sides by 7 to isolate n.

Answer:

So the answer is n=6%2F7 which approximates to n=0.857.
