Answer:
the third one
Step-by-step explanation:
Answer:
<h3>x = 4</h3>
Step-by-step explanation:
102 + 102 + 24x + 24x - 18 - 18 = 360
204 + 48x - 36 = 360
204 + 48x = 360 + 36
204 + 48x = 396
48x = 396 - 204
48x = 192
x = 192/48
x = 4
First step, expand the left side (multiply together) (apply FOIL/distribution property)
2nd step, solve so that one side is zero, by adding/subtracting like terms
3rd step, solve for x
<span>-10 < x - 9
</span><span>-10+9 < x - 9+9
-1<x, or
x> - 1</span>
