go to desmos.com and graph it. The points where it intersects on the X and Y axis is you solution set!

Graphical solution: (see attached for animated gif instructions) 1. go to http://www.desmos.com/calculator 2. Type in y = 2x-5 (don't copy-paste, just type it in) 3. Type in (3,11) (literally, type a parenthesis (, then 3, then a comma, then 11 then parenthesis), etc... 4. Type in your other points. Whichever point/s lie exactly on the line y = 2x-5 are solutions. :)
