We can prove it using 0 method 
0×0=0
0×2+0×2=0×5
0(2+2)=0(5)
ie 2+2=5

0

Simply, we can prove it by substituting 0.
TO PROVE: 2+2=5 (weird)
PROOF:
2+2+0=5 (a+0=a)
Therefore, 4+0=5 (2+2=4)
0=5-4=1 (transposing 4 to RHS)
So, we arrive at a conclusion that, 0=1 (super weird though)
Substituting this,
4+0=5
4+1=5
5=5
LHS=RHS
0
