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

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

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