Question 448617: please help me solve this equation.....n+n/3=600 i have tried a few ways but am not getting 450 like i am supposed to, i have tried...n+n/3=600 multiply both sides by 3 (n+n=1800)then i have (2n=1800) eliminate the 2 by divideing both sides by 2 which gives me N=900.... i have also tried the same thing with the N and got (N=600-N)...please help me figure this one out

n%2Bn%2F3=600 Start with the given equation.


3%28n%29%2Bcross%283%29%28n%2Fcross%283%29%29=3%28600%29 Multiply EVERY term by the LCD 3 to clear out the fraction.


3n%2Bn=1800 Multiply and simplify. This is where you made your mistake. You forgot to multiply the first 'n' by 3.


4n=1800 Combine like terms on the left side.


n=%281800%29%2F%284%29 Divide both sides by 4 to isolate n.


n=450 Reduce.

n + (n/3) = 600
Multiply by 3
3n + n = 1800
4n = 1800
n = 450
