Match the systems of equations with their solutions...

System of linear equations
x-y=25 2x+3y=180
2x-3y=-5 x+y/11=50
x-y=19 -2x+y/6=28
2x-y=-6 x-305/3=2y

Solutions
(-31,-56)
(51,26)
(47,33)
(-17,-36)

Had trouble reading your post.  It's important that you separate each equation with plenty of spaces, or, b etter yet, type only one equation per line:

x-y=19 -2x+y/6=28  should be:

   x-y=19
-2x+y/6=28  

Does (-31,-56) satisfy this system?  Is (-31) - (-52) = 19?  No.  Move on to the next system and check again whether or not (-31, -56) is a solution.

All you have to do is plug in the x and y for all equations to see which ones fit.

x-y=25 2x+3y=180 the solution is (51,26)

2x-3y=-5 x+y/11=50 the solution is (47,33)

x-y=19 -2x+y/6=28 the solution is (-17,-36)

2x-y=-6 x-305/3=2y the solution is (-31,-56)
