Answer this, it's a long overdue assignment .

13.) x=3

14.)

Step-by-step explanation:

13) plug the first equation into the second getting 3x-x-5=7 the add the x's, 4x-5=7 add five to both sides now you get 4x=12 then divide both sides by 4 getting x=3

14.) you have to add both equations vertically that gets you 5x+3y=14. then you have to solve.

5x+3y=14 subtract 3y from both sides getting 5x=14-3y divide by 5 both sides so, x=14-3y over 5 plug that into the equation and hopefully get your answers you need:)
