Answer:

No solution

Step-by-step explanation:

Assume x - 4 ≠ 0 and x + 5 ≠ 0,

note (x - 4)(x + 5) = x² + x - 20, so x² + x - 20 ≠ 0

Multiply by (x - 4)(x + 5) both sides and

get

x(x + 5) - 4(x - 4) = 36

x² + 5x - 4x + 16 = 36

x² + x - 20 = 0

But we have assumed x² + x - 20 ≠ 0

So the equation has no solution
