Answer:
x = 3
y = -2
Step-by-step explanation:
x + 2y = -1
2x – 3y =12
Using substitution means that in one equation you solve for a variable. In this case, the first equation would be easier to solve for x since there are no coefficients.
x = -2y - 1
Now, we plug in the value of x into the second equation, and solve for y.
2 (-2y - 1) - 3y = 12
-4y - 2 - 3y = 12
-7y - 2 = 12
-7y = 14
y = -2
Since we have a numerical value of y, we can use it to solve for x by plugging it into one of the original equations.
x + 2(-2) = -1
x - 4 = - 1
x = 3
If you'd like to check the answer, plug in both values you got to the original equations!
I hope this helps!

Answer:
20%
Step-by-step explanation:
Given:
Residents of a small city voted on whether to allow a developer to build a shopping center.
The number of votes in favor of the shopping center was 4,400.
The number of votes against the shopping center was 17,600.
Question asked:
What percent of the voters were in favor of building the shopping center ?
Solution:
The number of votes in favor of the shopping center = 4,400
The number of votes against the shopping center = 17,600
Total number of residents = 4,400 + 17,600 = 22,000


Thus, 20% of the voters were in favor of building the shopping center.
