Mathematics

no solution

substitute y = 2x + 4 into the other equation

2x - (2x + 4) = 6 ( distribute and simplify )

2x - 2x - 4 = 6 ( add 4 to both sides )

0 = 10 ← not possible

Hence the system has no solution

0.01 because it means 1 and 0.02 means 2. But 0.205 means 205 if you look at it like that.
