The Solution:

Given the system of equations below:

[tex]\begin{gathered} 6x+21y=103 \\ -6x+23y=51 \end{gathered}[/tex]

We are required to determine whether we should use addition or subtraction to solve the system of equations.

I will use addition to solve the system of equations.

Reason:

The coefficients of x in both equations are opposite in values and it is only the addition of the terms that can eliminate the terms in x.

Thus, the correct answer is 'addition'
