Kan noen hjelpe meg med å løse denne
14-b+2(3-3b)=
14-b+2(3-3b)=
14-b+2(3-3b)=
14-b+(2*3-2*3b)=
14-b+(6-6b)=
14-b+6-6b=
18-7b
Tror den skal være rett!!

bare en liten feil 
14-b+2(3-3b)=
14-b+(2*3-2*3b)=
14-b+(6-6b)=
14-b+6-6b=
18-7b <----- 20-7b
14-b+2(3-3b)=
14-b+(2*3-2*3b)=
14-b+(6-6b)=
14-b+6-6b=
18-7b <----- 20-7b
