Can you help me with #31?

3x - 4 = 2x + 2
3x - 4 + 4 = 2x + 2 + 4  (addition property of equality)
3x = 2x + 6 (simplification)
3x - 2x = 2x + 6 - 2x  (subtraction property of equality)
x = 6 (simplification)

aum · Answer

If you wish you can skip the simplification step and write it as follows:

3x - 4 = 2x + 2 
3x = 2x + 6  (addition property of equality) 
x = 6 (subtraction property of equality)
