To determine which ordered pair is a solution to the system of linear equations, we need to substitute each pair into both equations and see if they satisfy both equations.Let's start with the first pair:
Substituting into the first equation:
This is not true, so the first pair is not a solution.Next, let's try the second pair:
Substituting into the first equation:
This is also not true, so the second pair is not a solution.Now let's try the third pair:
Substituting into the first equation:
This is not true, so the third pair is not a solution.Finally, let's try the fourth pair:
Substituting into the first equation:
This is true, so the fourth pair is a solution.Therefore, the correct answer is C
