Question

I need to figure out how to solve for the compound inequality of -2(x+3)>9+3x

Answer 1

-2(x + 3) > 9 + 3x -- distribute through the parenthesis
-2x - 6 > 9 + 3x -- subtract 3x from both sides
-2x - 3x - 6 > 9 -- add 6 to both sides
-2x - 3x > 9 + 6 -- combine like terms
-6x > 15 -- divide by -6 and change the sign
x < - 15/6

Answer 2

however, that is not a compound inequality

Answer 3

Thats what I was thinking. I didnt think it was either. Its not for me actually its for my ex girlfriend. I was trying to tell her her teacher was wrong

Answer 4

How did you get the 6 in the second part?

Answer 5

when you distribute through the parenthesis...that means you multiply the number outside of the parenthesis, by everything in the parenthesis...
In other words..-2(x + 3) = -2 * x + (-2 * 3) = -2x - 6

Answer 6

understand ?

Answer 7

Ohhh ok thank you so much

Answer 8
