2x +2 + 3x - 6 = x + 3
5x - 4 = x + 3
5x - x = 4+3
4x = 7
X = 7/4
2 (x+1) + 3 (x-2) = x + 3 el 2 y el 3 multiplican lo que esta adentro ()
(2x + 1) + (3x -6) = x + 3
5x - 4 = x+3
5x - x = 3+4
4x = 7
x = 7/4
x = 1,75
Comprobación: Donde estaba x le damos el valor que encontramos
2 (1,75 + 1) + 3 ( 1,75 - 2) = 1,75 +3
2 (2,75) + 3 (-0,25) = 4,75
5,25 - 0,75 = 4,75
4,75 = 4,75
Buena suerte
