Answer:

[tex]x=2 , y=1[/tex]

Step-by-step explanation:

Since the second equation is fully simplified and we know what x equals, we plug the entire equation of x in for x in the top equation:

[tex]5(3y-1)+10y=20[/tex]

Now solve for y.

[tex]y=1[/tex]

Now plug y back into the bottom equation and solve for x.

[tex]x=3(1)-1[/tex]

[tex]x=2[/tex]
