Answer:b. (8,-1) is a solution to one equation but not the other, so it is a solution to the system
Step-by-step explanation:
27. Which statement is true about the system
x+3y=11
y=r-7
a. (8,-1) is a solution to both equations, so it is a solution to the system
b. (8,-1) is a solution to one equation but not the other, so it is a solution to the system
C. (8,-1) is a solution to one equation but not the other so it is not the solution to the system
d. (8,-1) is not a solution to either equation, so it is not a solution to the system
