Describing Steps in solving a Linear Inequality
Below you will find the completed steps to a problem with directions βSolve the linear inequality, show the
solution on a number line, and write the solution in interval notation.β Write a description of what happened in
each step and answer the questions.
Solve the linear inequality

2. 4π₯ β 12 < 2 β 9π₯ + 12
3. 4π₯ β 12 < β9π₯ + 14
4. 13π₯ β 12 < 14
5. 13π₯ < 26
6. π₯ < 2

Number line solution
Step one: place a ( or a [.
f) A parenthesis was placed on the line, is this
correct? Why or why not?
Step two: shade
