Please let me know if you need any clarification. I'm always happy to answer your questions.

4x+2y =5

3x+y =9 ---> y =9-3x

substituting the value of y in the first equation, we get

4x+2(9-3x) =5

4x+18-6x =5

-2x+18 =5

-2x =-13

x =6.5

so y = 9 - (3*6.5) = -10.5

Please let me know if you have any questions and best me if you are satisfactory.
