Answer:
C. No solution
Step-by-step explanation:
System of Equations:
A) 
B) 
Simplifying and rearranging equation A.
Dividing each term by 3 (common factor for each term) in equation A.


Subtracting both sides by 


Adding 7 both sides.

Adding the above equation to equation B.
+ 
We have
which is not true.
Hence the system has no solution. (Answer)
