The Triangle thats not unique is letter D
no of members who voted=
75/100x60=45members
no of members who did not vote=
60-45=15 members
3(5b-1)=5
Get rid of the brackets
15b-3=5
add 3 to both sides of the equation
15b=8
divide both sides of the equation by 15
b=0.53
4(3y-1)=20
12y-4=20
12y=24
y=0.5
