Cześć,pomóżcie mi !* oznacza mnożenie,a : dzielenie.Wyrażenia algebraiczne.
1.Uzupełnij :
6x-2*3=
6x-2:3=
6x-2+3=
6x-2-3=
6x-2*(jedna druga)=
6x-2:(jedna druga)=
6x-2-2=
6x-2+2=
6x-2*2=
6x-2:(-2)=
Dzięki ! :)

6x-2*3=6x-6
6x-2:3=6x-2/3
6x-2+3=6x+1
6x-2-3=6x-5
6x-2*1/2=6x-1
6x-2:1/2=6x-4
6x-2-2=6x-4
6x-2+2=6x
6x-2*2=6x-4
6x-2:(-2)=6x+1
Powinno być dobrze. :)
6x-2*3=6x-6
6x-2:3=6x-2/3
6x-2+3=6x(-2+3)=6x-1
6x-2-3=6x(-2+-3)=6x-5
6x-2*1/2=6x-(2*0,5)=6x-1
6x-2:1/2=6x-1
6x-2-2=6x-4
6x-2+2=6x
6x-2*2=6x-4
6x-2:(-2)=6x+1
