Does (3, 6) make the inequality x + y ≤ 9 true?

Hi

(x, y) = (3,6) ⇒ x=3 and y=6

x+y ≤ 9

3+6 ≤ 9

9 ≤ 9 ⇒ 9 is lower than or equal than 9? Yes, true, 9 = 9

Answer: (3,6) is a solution

If you would like to know if (3, 6) is a solution to the inequality x + y < = 9, you can calculate this using the following steps:

(3, 6) ... x = 3, y = 6

x + y < = 9

3 + 6 < = 9

9 < = 9

Result: (3, 6) is a solution to the inequality x + y < = 9.
