Solve for x: 4 − (x + 2) < −3(x + 4)

Answer 1

Hello @peanutball2001 and Welcome to OpenStudy! :)

to solve for x, first use the distributive property to get rid of the parenthesis
can you do that? :3

Answer 2

i can on the right side but not the left

Answer 3

that's ok
let's pretend the - (x + 2)
is just a + (-1)(x + 2)

so on the left we have 4 + (-1)(x + 2)
can you distribute the (-1) into the (x + 2) ? :)

Answer 4

-x and -2?

Answer 5

right!
so on the left we now have 4 - x - 2

Answer 6

okay so would you end up simplifying that to 2x?

Answer 7

hmm?
4 - x - 2 < -3x - 12 then add like terms
then add 3x to both sides

so yes kinda, you'll get 2x on the left
so what did you get on the right? :)

Answer 8

5x< -12??

Answer 9

no, the 2x was correct for the left side
4 - x - 2 < -3x - 12
2 - x < -3x - 12
+3x +3x
2 + 2x < -12 now add 2 to both sides :)

Answer 10

4+2x<-10

Answer 11

*scratches head* hmmm
OH
whoops >,<
sorry I meant to subtract 2 from both sides
2 + 2x < -12
-2 -2

Answer 12

x<-7

Answer 13

correct! :D
