Ax+By=C
Move +By to the other side. Sign changes from +By to -By.
Ax+By-By=C-By
Ax=C-By
Divide by A for both sides
Ax/x=C/x-By/x
A=C/x-By/x
Answer: A=C/x-By/x
Utilize PEMDAS to solve the problems.

Answer:
I think the answer would be -60 (as in 60 people left each year)
Step-by-step explanation:
If the population decreased by 300 over 5 years, and the same number of residents left each year, then you would divide 300 by 5, and that gives you 60.
Answer:
a: -3n+1
b:-5n-2
Step-by-step explanation:
a: it is -3+1 because you can see that the sequence is going down by 3, so it is the 3 times table, but because the number is 4, and 4 is 1 more than 3, you put plus one at the end. :)
b: similar to the last, it's going down by five, but it is two less this time, so you put minus two instead.
Hope this helps :),
