How about 20 plus 6 equals 26 as one example
Assuming you mean the tangent at x = 4 of x² + y² = 26 then: x² + y² = 26 → y² = 26 - x² → y = √(26 - x²) → slope = dy/dx = d/dx √(26 - x²) = -x/√(26 - x²) At x = 4: slope = -4/√(26 - 4²) = -1.26491106.... ≈ -1.265
n = 26

No answer in integers. Quadratic formula gives roots of x2 + x - 26 = 0 as 5.625 and -4.625
2 times 13 = 26 26 also = 1 squared + 5 squared
x2 = (26 + x)2 Taking square roots: x = +/-(26 + x) Then x = 26 + x or x = -26 -x The first gives a nonsense "equation" 0 = 26 but the second gives 2x = -26 or x = -13
15x26=390
It works out exactly as: 7 times the square root of 26

26 + 8 = 34
26, in that situation just add the negative number to the answer to find the variable
