#### Work Step by Step

For easier work, get rid of the fractions by multiplying the LCD of 5 to both sides to have: $\\5(\frac{2}{5}x +1) \lt 5(\frac{1}{5}-2x) \\2x+5 \lt 1-10x$ Add $10x$ to both sides to have: $\\2x+5+10x \lt 1-10x+10x \\12x+5 \lt 1$ Subtract 5 to both sides to have: $\\12x+5-5 \lt 1 -5 \\12x \lt -4$ Divide 12 to both sides to have: $\\x \lt \frac{-4}{12} \\ x \lt -\frac{1}{3}$
