With both inequalities and equations, you are solving for a variable by isolating it to one side.
A lot of properties that apply to equations apply to inequalities as well (addition property of equality, division property of equality, etc.)
<h2>Differences:</h2>
If you divide or multiply by a negative number, you must flip the inequality symbol. Dividing or multiplying by a negative number doesn't affect the equal sign.
When graphing the inequality, shaded regions (and the lines themselves if they're solid lines) are a part of the solution. When graphing an equation, only points on that line are solutions.
ok so we have (-9) in parentheses right? And positive 3 outside of parentheses so we know 9 x 3 = 27 BUT we have a negative in front of 9 so we just put -27.
Hope this helps :D ~P.s- pls could u give brainliest to meh TYSM!
