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
