2x + y = 14
3.)
Does this system of equations have one solution, no solutions, or an infinite number of solutions?
2y + 8x - 12 = 0
4x + y = -6
4 Solve this system of equations using the addition method.
5x + 2y = 19
x - 2y = -1
5.) Solve this system of equations using the addition method.

1.Does this system of equations have one solution, no solutions, or an infinite number of solutions?
2y + 8x - 12 = 0
4x + y = -6
--------
y = -4x+3
y = -4x-6
Parallel, so no solutions.
---------------------------------
2.)
Is (10, 2) a solution to this system of equations?
y = 5x
2x + y = 14
------
2 = 5*10::::::false
---------------------------------
3.)
Does this system of equations have one solution, no solutions, or an infinite number of solutions?
2y + 8x - 12 = 0
4x + y = -6
----------
y = 4x - 6
y = -4x - 6
--
Infinitely many solutions.
================================
4 Solve this system of equations using the addition method.
5x + 2y = 19
x - 2y = -1
-----------------
6x = 18
x = 3
-----
Solve for "y":
2y = x+1
2y = 4
y = 2
================================
5.) Solve this system of equations using the addition method.
5x + y = 6
2y = x +1
--------
10x + 2y = 12
x - 2y = -1
-----
Add:
11x = 11
x = 1
----
Solve for "y":
y = -5x+6
y = -5+6
y = 1
----------------------
