Solve by the elimination method.
5r-3s=2
3r 5s =42

in your first question, you found only the one variable, you still have to find s
Besides that, you have a typo in the second equation.
in your second problem,
the slope of the first equation is -4/5
the slope of the second one is 5/4
notice they are negative reciprocals of each other.
What did you learn about that situation?
