Answer:
(-6, +∞)
Explanation:
4(x + 2) - 5x < x + 20 Distribute the 4
4x + 8 - 5x < x + 20 combine like terms
-x + 8 < x + 20 Add x to both sides
-x + x + 8 < x + x + 20
8< 2x + 20 Subtract 20 from both sides
-12 < 2x Divide both sides by 2
<

-6 < x
x > -6
My solutions are all the numbers larger than -6.
