By 2020, California is expected to have 2 million more senior citizens than Florida, and the sum of the number of senior citizens in the two states is expected to be 12 million. Find the expected senior citizen population in Florida in 2020. a.
2x + 12 = 12; 0 million
c.
2x + 2 = 12; 5 million
b.
2x - 12 = 12; 24 million
d.
2x - 2 = 12; 7 million

here's a poem i finished a while ago. i hope you like it and that it inspires you.

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
