Given:
To select the option which is not a way to solve a system of equations.
Step-by-step explanation:
As we know,
A system of equations is being solved using the graphical method, substitution method, and elimination method.
So, the odd one is Transversal.
In geometry, a transversal is a line that intersects two or more lines at distinct points.
Thus, transversal is not a way to solve a system of equations.
Final answer: Transversal
