(6/7)(3-5n) ≥ (3/5)(1-9n)
Let's start by multiplying both sides by the common denominator of 7 and 5, i.e., 35.....this will clear the fractions
(35) (6/7)(3-5n) ≥ (35) (3/5)(1-9n) =
30 (3 - 5n) ≥ 21 (1 - 9n) simplify
90 - 150n ≥ 21 - 189n add 150n to both sides, subtract 21 from both sides
69 ≥ - 39n divide both sides by -39 and reverse the inequality sign
-69/39 ≤ n reduce the fraction by dividing top/bottom by 3
-23/13 ≤ n or written another way,
n ≥ -23 / 13
