Get the b all alone on one side of the inequality. To do this, we can divide both sides by 5. 5b / 5 ≤ -15 / 5 b ≤ -3 So, that means b has to be less than or equal to -3. In interval notation it would look like [-3, -∞) In a set builder notation: {x | x ∈ R, x ≤ -3} Which is read as the set of all x, such that, x is a member of the real numbers and x is less than or equal to -3.

5b≤-15 Divided 5 for both side 5b/5≤-15/5 b≤-3. As a result, b≤-3. Hope it help!
