6*(3*x-4)-5*(4-x)=12x+76(3x-4) - 5(4-x)= 12x+7
18x- 24 - 20 + 5x= 12x +7
18x+5x-12x= 7+24+20
11x= 51
x= 51 supra 11
x= 4, (63) - paranteza e perioada, daca rezolvi impartirea
9*(2x-3)-6*(5x+7)=1- 2x
9(2x-3) - 6(5x+7) = 1- 2x
18x - 27- 30x - 49= 1- 2x
18x-30x+2x= 1+27+49
-10x= 77
x= - 77 supra 10
x= -7,7
