note: 5≠20
also, if you multiply both sides of an inequality by a negative number, you flip te direction of the inequality sign
example: 3<5, multiply by -1, -3>-5
so given
-2<3
multiply both ides by -5 and fip sign
remember that (-)(-)=(-) and (+)(-)=(-)(+)=(-)
10>-15
4th option is answer
X² - 3x + 27 = 8x - 3 аdd 3 to both sides ⇒
+ 3 + 3
---------------------------
x² - 3x + 30 = 8x subtract 8x from both sides ⇒<span>
- 8x - 8x
--------------------------
x</span>² - 11x + 30 = 0 ← <span>standard form
</span>
A. Add 3 to both sides and subtract 8x from both sides.
