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
