Answer:
NO SOLUTION
Explanation:
Here you're asked to solve a system of equations, linear equations in this case.
Since y = 2x, we can subst. 2x for y in the 2nd equation:
-6x + 3(2x) = 16
Combining the x terms results in 0 = 16, which is never true.
Thus, this system of linear equations has NO SOLUTION.
