Question

Is d = 6 a solution to the inequality below?
13 < d + 3

Answer 1

Explanation:

d = 6 would not be a solution to the inequality below because it would make the inequality untrue! Plugging in, we get:

13 < d + 3

13 < 6 + 3
13 < 9
We know that 9 is not a solution to the inequality!

To solve, we isolate the d, and from there we can find all values that are a solution to the inequality to the solution!


`13 < d + 3\\\\13 - 3 < d\\\\10 < d`

Thus, one can say that the solutions to the inequality are: [R, d > 10]!
