Answer:
3) (0, 0)
4) (-1, 2)
Step-by-step explanation:
I find a graphing calculator provides a quick solution to a system of linear equations.
3) The solution is (x, y) = (0, 0)
4) The solution is (x, y) = (-1, 2)
__
In each case, the y-term can be eliminated by multiplying the first equation by 3. For problem 3) the resulting equations must be added. For problem 4), the resulting equations must be subtracted.
