Answer
y = 2x +8
Step-by-step explanation:
Add 2
x to both sides of the first equation to get:
y
=
8
+
2
x
Divide both sides of the second equation by 2 to get:
y
=
8
+
2
x
The two equations determine the same conditions on xy so this system of equations has an infinite number of solutions, namely all points on the line:
y
=
2
x
+
8
