Hey! Hopefully this helped :)
12, 6
First Simplify
3x - 30 = y
7y - 6 = 3x
Next, Eliminate One of the variables
6y = 36
Divide
y = 6
Substitute y and solve
-3x + 7 x 6 = 6
X = 12
Checker solution, not necessarily needed
3 x 12 - 30 = 6
7 x 6 - 6 = 3 x 12
6 = 6
36 = 36
12, 6 Is the Answer
or another way to put it is
(x, y) = (12, 6)
