Good idea to make that x term positive. To do this, add (3/5)x to both sides of the inequality:
12 - (3/5)x ≥ 39
+(3/5)x = (3/5)x Then
12 ≥ 39 + (3/5)x Now subtract 39 from both sides:
12 - 39 = (3/5)x, or -27 ≥ (3/5)x
Lastly, mult both sides by (5/3) to remove the (3/5):
-27(5/3) ≥ x, or x ≤ -45 (answer)
