Question

A system of equations has one solution when the lines represented by those equations intersect at exactly one point. This means that there is a unique pair of values that satisfies both equations simultaneously. Graphically, this is represented as the point where the two lines cross each other.

make this sound as an 8th grader

Answer 1

A system of equations has one solution when the lines they represent cross at just one point. This means there is one unique pair of values that makes both equations true at the same time. If you graph the two equations, you'll see them meet at one spot where they intersect. That's the only point that satisfies both equations!
