Answer: No it is not a solution
Why not? Because it doesn't make the first inequality true. Replace x with 1 and y with 2
y > 2x
y > 2*1 ... replaced x with 1
2 > 2*1 ... replaced y with 2
2 > 2 ... which is a false inequality statement since 2 is not larger than itself

Answer: NO!
Step-by-step explanation:
x = 1, y = 2
y > 2x
2 > 2 (1)
2 > 2
False
Sine it already failed, no need to check the other equation.
