Question

Find the solution of the linear inequality and express the solution set in set notation and interval notation. Graph the solution set on the real number line.

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

x + 1 < 8

Step 02:

Inequality:

x + 1 < 8

x + 1 - 1 < 8 - 1

x < 7

set notation

x ∈ R

interval notation

(-oo , 7)

graph

That is the full solution.
