ciao!

5[2(x-3)-3(x+2)]=4(x-4)+3

5[2x -6 -3x -6]= 4x -16 +3
10x -30 -15x -30 = 4x -16 +3
10x -15x -4x = 30+30-16+3
-9x=47
x= - 47/9


2(1-x)-3=3(x-3)-4-2x

2 -2x -3 = 3x -9 -4 -2x
-2x -3x +2x = -2 +3 -9 -4
-3x = -12
x= 12/3 = 4

[math]\frac{15x+10}{8}[/math]

Minimo comune multiplo 24, quindi:

32x +8 +16x +16 = 45x +30
32x + 16x -45x = -8 -16 +30
3x = +6
x= 6/3 = 2
