Firstly, try using FOIL to open up the brackets and collect like terms

@FireKat97 what is FOIL
FireKat97
  • FireKat97
okay so FOIL is a method with which you can open and simplify brackets so assume... a (b + c) so to simplify this you would do (a)(b) + (a)(c)

so 4-x + 4 - 2 < -3•x +-3•4 @FireKat97

  • FireKat97
your right hand side is correct however your left hand side isn't quite there, so when you have 4 - (x + 2) think of it like this 4 -1(x + 2) so what you are actually doing is 4 -(1)(x) + (-1)(2)

i think you simplify by getting common terms together ....the greater or less than symbol is like a equal sign so simplify
FireKat97
  • FireKat97
Your right hand side is correct however, reconsider your signs for the left hand side
