Question 969294
3x=-4y+15 --> 3x + 4y = 15
8y=-6x+30 --> 6x + 8y = 30
=================
3x + 4y = 15
6x + 8y = 30 Divide by 2 --> 3x + 4y = 15
-----------------
3x + 4y = 15
3x + 4y = 15
-------------------- Subtract (elimination)
0 = 0
It's the same equation twice --> dependent.
No unique solution.
