1/4 - (2x - 1)/2 = (x + 2)/3 

mmc(2,3,4) = 12

3 - 12x + 6 = 4x + 8 

3 + 6 - 8 = 4x + 12x

16x = 1

x = 1/16 

----------------------------------------------------------------------------------------------

2x² + x.(x + 2) – (x + 3).(x – 3) = 2.(x + 1)² 

2x²  + x²  + 2x - x²  + 9 = 2x²  + 4x + 2 

2x = 7

x = 7/2
