Question

Which of these is a simplified form of the equation 7x + 4 = 5 + 3x + 1x? 3x = 9 3x = 1 11x = 9 11x = 1

Answer 1

- I believe the answer is 3x=1 
I did this as my equation... 7x+4=5+3x+1x
          7x+4=5+4x
               -4  -4
                -------
          7x    = 1+4x
         -4x          -4x
         ----------------
         3x  =  1

- Answer option #2: 3x=1

Answer 2

7x + 4 = 5 + 3x + 1x
combine like terms first

7x + 4 = 5 + 4x
move the 4x over to the left side
3x + 4 = 5
Move the 4 over to the right side
3x = 1 is the answer
