I only figured out the answer for the Dorthy question, the answer is 210
in 1980 it was about 20%
in 1990 it was about 30%
about a 10% increase
in 2000 it was just under 40% so almost a 10% increase
so for estimating you can say it is increasing by about 10% every 10 years
so in 2010 you can estimate about 50% are unmarried

x=4
Substitute x in one of them
2(4)+y=10
y=10-8
y=2
