Solve for x: 4 − (x + 2)

Question

Solve for x: 4 − (x + 2) < −3(x + 4) x < −7 x > −7 x < −9 x > −9

whpalmer4 · Answer

$$4 - (x+2) < -3(x+4)$$Start by distributing:
$$4 - x - 2 < -3x -12$$At this point, I would add $3x$ to both sides.  Then add or subtract to get the numbers on the other side of the inequality sign.  Finally, do any division needed to get $x$ by itself.  Remember, if you multiply or divide by a negative number, you need to change the direction of the inequality sign.

What do you get after you add $3x$ to both sides.  Do not under any circumstances answer "idk" or "iono"

4 − (x + 2) < −3(x + 4)   distribute
  4 - x - 2  <  -3x - 12    add 3x to both sides
    +3x           +3x
     2x + 2  <  -12           then subtract 2 from both sides
           -2        -2
                                      then divide both sides by 2
       /2           /2
