What value of x is in the solution set of 9(2x + 1) < 9x – 18?
a: -4
b: -3
c: -2
d: -1

For this case we have the following inequality:

Solving the inequality we have:

Distributive property:

Combine similar terms:

From here, we clear the value of x:

Therefore, the solution is given by:

(-∞, -3)

The point that belongs to the solution is:

The value of x is in the solution set is:

A: -4
