I will go about solving this using the elimination method.
First, convert the equations.
10x + y = -20
4x + y = -12
Second, find the easiest variable to get rid of and get rid of it! (In this case, y) We will subtract to get rid of y.
6x = -8
Third, you want to solve the equation.
6x = -8 (divide by 6)
x =
Fourth, solve for y by inserting the answer for x into one of the equations.
10() + y = -20
+ y = -20 (subtract )
y =

Answer:
<h2>800%</h2>Step-by-step explanation:
Let p represent the population
in 1965 → the population becomes 2p
in 1970 → the population becomes 2(2p) = 4p
in 1975 → the population becomes 2(4p) = 8p
p ——————> 100%
8p ————-—-> x%
then
