Understanding the Equation x = 4

The video tutorial explains how to find integer solutions for the equation x=4 and graph them. It demonstrates that the x-coordinate must always be 4, while y can be any integer. Three solutions are found: (4,0), (4,1), and (4,2). These points are plotted on a coordinate plane, showing a vertical line at x=4. The tutorial concludes by noting that any equation of the form x=c results in a vertical line at c on the x-axis.
