Question

Line M is represented by the following equation:

x – y = 8

Which equation completes the system that is satisfied by the solution (18, 10)? (4 points)


x – y = –28
2x – 2y = 36
x + y = 18
2x – y = 26

Answer 1

Answer 2

plug (18,10) into each equation until you get an answer of the form x = x
for example, 2x-2y=36
2(18)-2(10)=36
36-20=36
16=36 so not the answer

Answer 3

okay...
