For two linear equations to have exactly one solution, their gradient/slope must be different. That's the only requirement. For example y=x intersects with -1/3x - 8 at (-6, -6). So one that has only one solution could be y=x+5.
For two linear equations to have no solutions they must have the same gradient/slope but not be the same equation. Hence, y = -1/3x + 8 would never intersect with y = -1/3x - 8.
For two linear equations to have infinite solutions, they must be the same line or simplify to give the same line. I.e. 3y = -x - 8 would have infinitely many solutions with the above graph.

Step-by-step explanation:
7(x-2y)= seven times(7x) the difference(-) of x and twice y(2y).
Answer:
The reciprocal is 25/12, therefore the number is 12/25, because 2 x 12 equals to 24, then plus 1, equals to 25, then it's 25/12. Not the best explanation but, better than no answer.
