MULTIPLE CHOICE QUESTION

7x - y = 10
-7x + y = -14
No Solution
(4, 1)
Infinitely Many Solutions
(2, -4)
Answer explanation
7x - y = 10
-7x + y = -14
All of the like terms have opposite coefficients, so both variables will be eliminated when we add the equations together. We cannot eliminate one without the other.
We are left with:
0=-4
This is a contradiction (false), so there is NO SOLUTION.
