Answer:
The given equation cannot be solve but can be simplified.
Step-by-step explanation:
Given equation: 5x-6y+87z = 6x+96y-867z
We can only simplify the equation, but we cannot solve because there are three unknown variables and only one equation.
To successfully solve, we requires minimum of three equations.
lets simplify it:
5x - 6x -6y - 96y +87z +867z =0
-x-102y+ 953z =0
⇒ x +102y + 953z =0
Which is the required simplification.
