Question

ecuacion
2x-3/4+2x-3/3=-1

Answer 1

2x - 3/4 + 2x - 3/3 = - 1 
2x - 3/4 + 2x = -1 + 3/3
2x - 3/4 + 2x = 0
2x + 2x = 0 + 3/4
2x + 2x = 3/4
4x = 3/4
x = 3/4 : 4
x = 3/16 

Comprobamos:
2x - 3/4 + 2x - 3/3 = - 1
2 . 3/16 - 3/4 + 2 . 3/16 - 3/3 = - 1
3/8 - 3/4 + 3/8 - 3/3 = - 1
- 3/8 + 3/8 - 3/3 = - 1
0 - 3/3 = - 1
-1 = - 1
