how do you write the solution of 5 + d < 8?

To solve the inequality 5 + d < 8, you need to isolate the variable "d" on one side of the inequality sign, so you can see what values of "d" make the statement true.

First, you can subtract 5 from both sides:

5 + d - 5 < 8 - 5

Simplifying, you get:

d < 3

Therefore, the solution to the inequality 5 + d < 8 is all values of "d" that are less than 3. In interval notation, this can be written as (-∞, 3).
