Hey there! :)
Equation 1) -2x + y = 14
Equation 2) 4x - 6y = 4
Add 2x to both sides of equation 1 so that we can get the value of y.
y = 2x + 14
Now, plug the value of y into our second equation.
4x - 6(2x + 14) = 4
Simplify.
4x - 12x - 84 = 4
Add 84 to both sides.
4x - 12x = 4 + 84
Simplify.
-8x = 88
Divide both sides by -8.
x = -11
Now, plug our value of x into our first equation in order to find y.
-2x + y = 14
-2(-11) + y = 14
22 + y = 14
y = -8
Therefore, the systems of equation variables are : (-11, -8)
~Hope this helped! :)

Answer:
See answers below.
Step-by-step explanation:
A relation is a function if the x-value in group of ordered pairs is only used one time.
1. Not a function: The x-value 4 was used twice.
2. Yes, it is a function: Each x-value was used one time.
3. Not a function: The x-value -2 was used twice.
4. Yes, it is a function: Each x-value was used one time.
5. Not a function: Each x-value -1 and -2 were used twice.
6. Not a function: The x-value 1/2 was used twice (1/2, 0) and (1/2, 1).
