Question

a) 2(x+1)+3(x-2)=4(6-5x)-3
b)4x-9+2(2-3x)=5-3(x-4)
c)12(x-3)+5(3-4x)=-7(x+2)
d)2[3(x-5)+x]=4(x-3)-3(x+1)-1

Answer 1

a) 2x+2+3x-6=24-20x-3
   2x+3x+20x=24-3-2+6
   25x=25
   x=25/25
   x=1
b)4x-9+4-6x=5-3x+12
  4x-6x+3x=5+12+9-4
  x=22
c)12x-36+15-20x=-7x-14
   12x-20x+7x=-14+36-15
    -x=7
aici nu stiu sigur daca am ous semnele corect imi pare rau
d)2(3x-15+x)=4x-12-3x-3-1
  6x-30+2x=4x-12-3x-3-1
  6x+2x-4x+3x=-3-1+30
  7x=26
    x=26/7
  aici m-am incurcat nu mai stiu cum e 
Imi cer scuze
Sper sa te fi ajutat
