The equations y=x+4 and y=12x8y=21x8 form a system of linear equations. The table below shows the y-value for each equation at six different values of x.

xy=x+4y=12x80482274066258441063
What can you conclude from the table?

A. The system has one solution, when x=0.

B. The system has one solution, when x=4.

C. The system has one solution, when x=8.

D. The system has no solution.

A solution to the system is when y has the same value in both equations for the same value of x. We see that is only true when x=8.
