If the lines are parallel (have the same slope but different intercepts) . . . no solution, because they never cross.
If the lines have different slopes . . . one solution, because they have exactly one common point.
If the lines have the same slope and the same intercept . . . infinitely many solutions, because every point on one line is also a point on the other line, one lays right on top of the other, and when you look at them on the graph, it looks like only one line.
one solution or no solution or an infinite number of solutions
A system of linear equations in two variables can have no solutions, one solution, or infinitely many solutions. The type of solution depends on the relationship between the lines represented by the equations. No solutions occur with parallel lines, one solution with intersecting lines, and infinitely many solutions occur with overlapping lines.

Jawaban:[tex] \frac{1}{6} [/tex]Penjelasan dengan langkah-langkah:[tex] \frac{5}{6} - \frac{2}{3} \\ = \frac{5}{6} - \frac{2 \times 2}{3 \times 2} \\ = \frac{5}{6} - \frac{4}{6} \\ = \frac{5 - 4}{6} \\ = \frac{1}{6} [/tex]
