The equations y=-x+4 and y=12x−8y= 21x−8 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=12x−804−822−740−66−2−58−4−410−6−3
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.
