Answer:

x ≤ 8

Step-by-step explanation:

5x + 20 ≤ 60

5x ≤ 40

x ≤ 8

Answer:

x = (-infinity, 8], or x <_ 8

Step-by-step explanation:

Just like with equalities, we can add or subtract anything from both sides of an inequality, and it will still be true. So, our first step is:

5x + 20 ≤ 60

becomes

5x ≤ 40

Next, we can divide both sides by 5 to isolate the variable on the left hand side of the inequality. So,

5x ≤ 40

becomes

x ≤ 8

This means that x can be any number less than or equal to 8.

x ≤ 8

x = (-infinity, 8]
