Rozwiąż równania:
a) (x+2) * 6 = 0.5x
b) 0,1(x+2) = 0,2x
c) 6(1-1/3x) = 2(1+1/2x)
d) 0,3x- 2(0,1x + 1) = 0
e) 0,5 (x - 3)+ 0,25(2x +6) = 5
Błagam pomóżcie.! :)

a) (x+2) * 6 = 0.5x
6x+12=0,5x
5,5x=-12
x=-12:55/10
x=-120/55=-2i10/55=-2i2/11
b) 0,1(x+2) = 0,2x
0,1x+0,2=0,2x
-0,1x=-0,2
x=2
c) 6(1-1/3x) = 2(1+1/2x)
6-2x=2+x
-3x=-4
x=4/3=1⅓
d) 0,3x- 2(0,1x + 1) = 0
0,3x-0,2x-2=0
0,1x=2
x=20
e) 0,5 (x - 3)+ 0,25(2x +6) = 5
0,5x-1,5+0,5x+1,5=5
x=5
