There is no solution.
To solve it using the substitution method, substitute y from the y = 3x - 4 equation into the 9x - 3y = 14 equation, like so:
9x - 3(3x - 4) = 14
Then after foiling:
9x - 9x -12 = 14
Since there are two x's on the same side, we can just cancel them out leaving:
-12 = 14
Since -12 most definitely does not equal 14, the equation has no solution.

Answer:
The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
