Sublimation has no connection to systems of equations. Putting sublimation and elimination together suggests you are confusing completely separate topics. Maybe you are dealing with chemical synthesis.


---Did you mean, "substitution"?

One of your equations is already y in terms of x. Substitute into the other equation:

2x%2B%28-x%2B5%29=11
2x-x%2B5=11
x%2B5=11
x=11-5
highlight%28x=6%29

Use the first equation to evaluate y:
y=-x%2B5
y=-6%2B5
highlight%28y=-1%29
