Mi serve aiuto per dei esercizi

[Christianverlezza]

1) 12(x-5) -(7x-4) =x+3(2 +4x-6) +8
2 3(-2x-6) +2(3x+5) -9x=11 -5x+2(7 -3x) -1

[butterfly.04]

12(x-5) -(7x-4) =x+3(2 +4x-6) +8
12x-60-(7x-4) = x+3(-4+4x)+8
12x-60-7x+4=x-12+12x+8
-60-7x+4=x-12+8
-56-7x=x-4
-7x-x=-4+56
-8x=52
x= -13/12

3(-2x-6) +2(3x+5) -9x=11 -5x+2(7 -3x) -1
-6x-18+6x+10-9x=11-5x+14-6x-1
-18+6x+10-9x=11-5x+14-1
-8-3x=24-5x
-3x+5x=24+8
2x=32
x=16

12(x-5)-(7x-4)
=x+3(2 +4x-6) +8
12x-60-(7x-4)
= x+3(-4+4x)+8
12x-60-7x+4

-60-7x+4
=x-12+8
-56-7x
=x-4
