Answer
y = 2x +8
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
