Final answer:
The question involves finding a formula from a system of equations. Algebraic manipulation like substitution or elimination is required, but the information provided is insufficient for a complete solution.
Step-by-step explanation:
The question appears to involve finding a general formula based on a system of equations provided. The equations provided are:
- yp + xq = xyz
- 2(x² - y²)p - yz(z² + xy)q = x´
- z(p - 9) = z² + (x + y)²
To find a formula that fits these equations, one would generally look for a way to express one of the variables in terms of others or to solve the system of equations. Usually, this involves algebraic manipulation methods such as substitution, elimination, or using matrix operations if applicable.
An example of the solving process could be to express 'p' from the first equation in terms of 'x', 'y', and 'z', and then proceed to substitute this value into the other two equations to further simplify them.
From the provided context and the nature of the equations, this seems to be a complex algebraic problem that would likely require a detailed understanding of algebraic techniques, possibly at the advanced high school level in subjects such as precalculus or calculus. Without further context or a specific aim, it is challenging to provide an exact formula, as the equations provided do not seem to have enough information for a complete solution.
