Question

Part 1: Solve the inequality 12 + x  2x - 2 and show all of your work. You can use <= to represent the less than or equal to symbol.

anonymous · Answer

put x variables on one side plain numbers on the next
view the x as an equal sign then work as regular algebraic equation
12+2 = 2x
      14= 2x 
       2     2
        7= x
       x <=7
you got seven by dividing both sides by two.  when you divided 2x by two you cancelled out both twos leaving you with x and when you divided 14 by 2 you got 7. Understand
