Answer:
the system has no solution. Letter "C"
Step-by-step explanation:
In order to solve this system we will multiply the first equation by "-2" and the second by "5". We have:
5*x + 5*y = 20 *(-2)
2*x + 2*y = 8 *(5)
-10*x -10*y = -40
10*x + 10*y = 40
We now sum both equations:
0 + 0 = 0
Since all the variables got cancelled by the sum the system has no solution. Letter "C".
