Hey!
Assuming that we're looking for a solution, (in some cases) it's typically easy to line your equations up with "matching terms." Like so:
-10x + 3y = 5
x - y = -4
The next step would be try to get one variable to cancel! This can be done using either elimination or substitution. In this problem, however, we can use substitution since we are already given a variable (x) = something else. Let's substitute x into our other equation!
We have x = y -4
-> *substitute y -4 into the other equation!
-10(y-4) + 3y = 5
-> now solving for y!
-10y + 40 +3y = 5
-7y = -35
y = 5.
You now have part of your solution! The y-value. I think you know what to do next. Let me know if you have questions!
