Very nice presentation!
Kinda looks like the infield surrounding a baseball diamond.
it’s easy. done in my head from the thumbnail. all one has to realize is that the first equation is equivalent to 2 x 10^(logx x logy) = 2 => logx x logy = 0
logx = u => x = 10ᵘ logy = v => y = 10ᵛ 10ᵘᵛ + 10ᵘᵛ = 2 =>10ᵘᵛ = 1 => uv = 0u = 0 ∨ v = 0 => x = 1 ∨ y = 1x = 11 + y^logy = 11 => y^logy = 10(logy)² = 1 => y = 10 ∨ y = 1/10y = 11 + x^logx = 11 => x^logx = 10(logx)² = 1 => x = 10 ∨ x = 1/10(x, y) = {(1, 10); (1, 1/10); (10, 1); (1/10, 1)}
was my way too.
This problem looks crazy. Definitely requires substitution.
