go to WWW. HelpTeacher.com. Type in the type of math you are doing, and it should pull up some examples to help you with that. Hopefully it will.
Given are:
250 adults and 180 parents
so we can solve the number of not parents
not parents = 250 - 180
not parents = 70
then we can number of people of votes for no
no not parents = 70 - 40 = 30
no parents = 180 - 150 = 30
yes no
parents 150 30
not parents 40 30
x=6
if you multiply 4 by whats inside the parenthesis you get 5x+16x+44=170
next combine like terms and get 21x+44=170
next subtract 44 from itself and 170 to get 21×=126
finally divide 21 from both sides and you get x=6
hope this helps!
