(Assuming that X=x,) from 3X-7=2X+8 you get X.
Substituting, you also get Y.

Bye.

To see the math work by setting Y equations equal to each other, go here:

1 unknown variable equations

Enter your equations and see the math.

Also, if 2 unknowns can be solved by Substitution, Elimination, or Cramer's method, but in this case, the above method is the best since both Y coefficients equal each other.
