Joe solved this linear system correctly.

6x+3y=6

y=−2x+2

These are the last two steps of his work.

6x−6x+6=6

6=6

Which statement about this linear system must be true?

a) x must equal 6

b) y must equal 6

c) there is no solution to this system

d) there are infinitely many solutions to this system

I think either B or D

this means that the two lines are collinear so when you plot them on the same set of axis, they will appear as one line
