I divided eq1 by 3 and added 4y to both sides (also in eq1).

when you have two functions y=f(x) and y=g(x) then, the solutions are the x-values that satisfy g(x)=f(x). If f(x)=f(x), then it is equivalent for all x values.

here, our f(x) and g(x) are also same. So for both y and x, we have how many solutions?

=we have 1 solution
