How do you want to solve them? Solve for a variable and substitute into other equation, and use value to find other variable.

5x=-2y-1
x=-%282y%2B1%29%2F5
-
3%28-%282y%2B1%29%2F5%29%2B7y=11
-3%282y%2B1%29%2B35y=55
-6y-3%2B35y=55
29y=55%2B3
29y=58
highlight%28y=2%29


Now, what is x?
x=-%282%2A2%2B1%29%2F5
highlight%28x=-1%29
