"best" is not a good term for this since different people have different ways of figuring things out

amistre64 · Answer

if it means "the most efficient" way, then there is a solution that will take the least amount of steps to solve

amistre64 · Answer

of the remaining options, which one do you think would actually eliminate a variable?
