Question

PLEASE HELP which statement is true about the system x-3y=5 and y=x-7

A. (8,1) is NOT a solution to either equation so it is not a solution to the system
B. (8,1) is a solution to one equation but not the other one so it is not a solution to the system
C. (8,1) is a solution to both equations so it is a solution to the system
D. (8,1) is a solution to one equation but not the other one so it is a solution to the system

Answer 1

Answer: C

Explanation:

x-3y=5, y=x-7 *solve it

the answer is (8,1)

so..

C. (8,1) is a solution to both equations so it is a solution to the system
