A) 4(x-1) =6(1+x)
4x-4=6+6x
4x-6x=6+4
-2x=10 /: (-2)
x= -5
B) 4(3x+2)+5(2x+3=-(2x+13)
12x+8+10x+15= -2x-13
22x+2x= -13-8-15
24x= -36 /: 24
x= -1 i 1/2
C)x/3+2=7 /×3
x+6=21
x=21-6
x=15
4x - 4 = 6 + 6x
4x - 6x = 6+4
-2x= 10/ :-2
x = - 5
12x + 8 + 10x + 15 = -2x -13
12x + 10x + 2x = -13-15 -8
24x = -36 /:24
x = -1,5
x\3 = 7 -2
x/3 = 5 /:x/3
x = 15
chyba dobrze
