Answer:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).
Step-by-step explanation:
Answer:
x + y = 2.
2x + 2y = 24.
Step-by-step explanation:
The equations' lines on the coordinate grid are the same. One equation is a multiple of the other. Any point on the line is a solution so there are infinite solutions.
Example:
x + y = 12
2x + 2y = 24
The second = first one * 2.
