I don't see anything to solve. I suspect some of the problem is missing.
If you are supposed to graph the lines represented by those equations, they're just all vertical lines at the given x-coordinates.
If you are supposed to plot the values on the number line, just place dots at the given values.
Solve.
• x = 2
• x = –2
• x = 28
• x = –28
How?

Solve.
(2/x) + (12/x) =7
• x = 2
• x = –2
• x = 28
• x = –28
