First eliminate the mixed number on the right.
Then give the two fractions a common denominator. (This is not necessary, but it makes the solution clearer.) To do this, multiply the right side by 3/3.
Next, multiply both sides by -21. When you multiply by a negative you must flip the sign.
Next, divide both sides by 10
n < 5.4
We can check that this answer is reasonable by plugging in 5 and 6 for n in the original equation.
Correct.
Incorrect.
So our answer of n < 5.4 is not unreasonable, and thus we can accept it as the correct answer.
