To solve this equation, we can first simplify it:

Х + х + х * х = 24

This can be rewritten as:

3х + х^2 = 24

Now, we can rearrange the equation:

x^2 + 3x - 24 = 0

Next, we can factor the quadratic equation:

(x + 8)(x - 3) = 0

Setting each factor to zero, we find two possible solutions for x:

x + 8 = 0 => x = -8
x - 3 = 0 => x = 3

Therefore, the possible values for x in the equation Х + х + х * х = 24 are x = -8 and x = 3.
