$x \gt -3$

Work Step by Step

Inequality: $3x+5 \gt -4$ Add 5 red tiles to each side: $3x+5 +(-5) \gt -4 + (-5)$ Simplify by removing the zero pairs. $3x \gt -9$ Divide each side into two equal groups. $\frac{3x }{3}\gt \frac{ -9}{3}$ Each green tile is greater than three red tiles, so $x \gt -3$. $x \gt -3$
