To solve the inequality 5x - 10 ≤ 20, we need to isolate the variable x.
First, we can start by adding 10 to both sides of the inequality to get rid of the -10:
5x - 10 + 10 ≤ 20 + 10
Simplifying, we have:
5x ≤ 30
Next, we can divide both sides of the inequality by 5 to solve for x:
(5x) / 5 ≤ 30 / 5
Simplifying further, we get:
x ≤ 6
Therefore, the solution to the given inequality is x ≤ 6.
