    Solve it like an equation but remember that the inequality changes if you divide or multiply by a negative number.

    I am new to this, could you help me do this problem? If I solve it like an equation... where do I start?

    Ok, so the first inequality is \[12x \ge 16-4\] \[12x \ge \] \[x \ge \frac{ 12 }{ 12 }\] \[x \ge 1\]

    \[3x \le -14+5\] \[3x \le -9\] \[x \le \frac{ -9 }{ 3 }\] \[x \le -3\]

    Just ask questions if you have any. Graphing it is actually really simple, do you know what a numberline is?

    Yes, I know what a number line is. I think I know how to do it now. Thanks for your help!
