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!

Given that the line segments NU and US can also be written as line segment NS then Point U would satisfy the Definition of Betweenness.
This simply means that Point U lies between Points N and S along the same line.
