x = 8
x = 12
y = 6
Step-by-step explanation:
The first two lines are both horizontal and parallel, and they never touch, going on forever.
The third line is straight and vertical, intersecting with both parallel lines at a 90-degree angle, making it perpendicular.
The same would occur if you made the top two into y equations and the bottom one an x equation.
I hope this helps!
