What a simultaneous solution means

What a simultaneous solution means

Graph of the lines 2x + y = 7 and x - y = -1 crossing at the solution point (2, 3)

Each linear equation is a straight line, and the simultaneous solution is the point where the lines cross. A solution pair must make both equations true at the same time.
