Question

rezolvati ecuatiile
-2(x-3)-3=x-2
4(3-x)+2(x-5)=-3x+11
-3(4x-3)+2(3x+5)=-4(2x+15)-4
2-x/3-6=x-1/2
(x+2)²/2-(x-3)(x+3)/3=2x-1/2+(x-1)²/2

Answer 1

-2x-6-3=x-2
-2x-6-3=2x
-2x-2x=6-3
x=3

Answer 2

1)-2(x-3)-3=x-2
-2x+6-3-x+2=0
x=5/3
2)4(3-x)+2(x-5)=-3x+11
12-4x+2x-10+3x-11=0
x-9=0
x=9
3)-3(4x-3)+2(3x+5)=-4(2x+15)-4
-12x+6x+8x=-9-10-60-4
2x=-83
x=83/2
4)2-x/3-6=x-1/2
-4+1/2=x+x/3
-7/2=4x/3
x=21/8
