3x=6
x=2

5y=20
y=4

The only problem with those equations is that if you plug in other numbers other than 2 & 4 respectively, it automatically becomes falsified expressions. For example, 4spooky6u cannot be found if you plug in 4 & 6 respectively to the equations you mentioned.

A good step forward, however. We'll soon discover all the spooky equations.
