Answer 4

what defines a set of coincident lines?

Answer 5

what do you mean

Answer 6

its your question, not mine ....

"the system of equations is coincident"

define coincident lines for me

Answer 7

Two lines or shapes that lie exactly on top of each other.

Answer 8

good, now in this case, when one equation is a scaled version of the other, they are coincident:

x + y = c and n(x + y = c)

Answer 9

3x + y = 7 is coincident to: 3nx + ny + 7n

but we are given that 3nx = 9x, so what is n?

Answer 10

* = 7n typoed that little bit
