Question

1. 4x+y=6
y=6-4x

Answer 1

Is that the complete question ?

Answer 2

You need to find out x? (:

Answer 3

subtract to eliminate y
4x = 4x
these two equations are the same
no solutions

Answer 4

if you add 4x to both sides of second equation you get
4x + y = 6

- same as first equation

Answer 5

Strictly, there are no solutions when lines are parallel.

If the equations are the same line then it is conventionally said that there are an infinite number of solutions.

Answer 6

right

Answer 7

i forgot that

Answer 8

both the lines are coincident ,,,,,, they have solutions all in common... or i think u wrote the Q again....whatever it is...they are coincident hope u understood
