-5u + 5 ≤ - 15

Answer 1

To solve the inequality, we need to isolate the variable 'u'.

-5u + 5 ≤ -15

First, subtract 5 from both sides of the inequality:

-5u + 5 - 5 ≤ -15 - 5

-5u ≤ -20

Next, divide both sides by -5. Remember when we divide an inequality by a negative number, we need to flip the inequality sign:

-5u / -5 ≥ -20 / -5

u ≥ 4

So the solution to the inequality is u ≥ 4.
