Question 753823
3x + 6 = 7 - 2x
Collect unknowns on left
knowns on right, remembering to 
change the sign as you change
the side.
3x + 2x = 7 - 6
     5x = 1
      x = 1/5
You can check your answer by 
putting the x value into your 
equations.
3x + 6 = 7 - 2x
3(1/5) + 6 = 7 - 2(1/5)
3/5 + 6 = 7 - 2/5
      33/5 = 33/5

Hope this helps
:-)
