$r \geq - 2$ $r>=-2$

Explanation:

$isolate 4 r by subtracting 3 from both sides$ $"isolate "4r" by subtracting 3 from both sides"$

$- 5 - 3 \leq 4 r$ $-5-3<=4r$

$- 8 \leq 4 r$ $-8<=4r$

$divide both sides by 4$ $"divide both sides by 4"$

$- 2 \leq r or r \geq - 2 is the solution$ $-2<=r" or "r>=-2" is the solution"$

$r \in [- 2, \infty) \leftarrow in interval notation$ $r in[-2,oo)larrcolor(blue)"in interval notation"$
