Given the inequality:

15x - 20 < 130

Solve the inequality.

Solution:

In order to solve the inequality, we first transpose - 20 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

15x - 20 < 130

15x < 130 + 15

15x < 150

Divide both sides by 15 in order to determine the value of x.

15x/15 < 150/15

x  < 10

Final answer:

x < 10
