Answer:
y = 2
x = -3.5
Step-by-step explanation:
3y and (2x + 13) are same-side angles.
that means they are equal
(that's not the real term for it, I just forgot what it's called)
using that, you can make this equation:
3y = 2x + 13
3y - 13 = 2x
(3y - 13)/2 = x
(5y - 4) and 3y are vertical angles.
vertical angles are equal.
using this, you can make the following equation:
5y - 4 = 3y
5y - 3y - 4 = 0
5y - 3y = 4
2y = 4
y = 2
now, substitute y for 2 in the original equation.
(3y - 13)/2 = x
(6 - 13)/2 = x
-7/2 = x
-3.5 = x
