Answer:
No solution would mean that there isn't an answer to the equation. it would be impossible for the equation to be true. Infinite/many solutions means that any value for the variable would make the equation true.
Example:
No solution:
0 = 0, x = x
2x + 4y= 8
x + 2y = 4
Many solutions:
2 = 5
3x + 2y = 5
6x + 4y = 8
