[6.02] and [6.03] What is the value of the x variable in the solution to the following system of equations?

3x + y = 1
6x + 2y = −9

0

2

There is no x value as there is no solution to this system

x can be any value as there are infinitely many solutions to this system

help please

solve to find x.. use substitution.
3x+y=1
subtract y from both sides and subtract 1 from both sides.
what will you get?

im not sure
i don't understand

smokeysthename · Answer

let me go slower.
looking at the first equation only right now.. 3x+y=1
subtract y from both sides.

anonymous · Answer

okay

smokeysthename · Answer

you'll get 3x=-y+1
now subtract 1 from both sides. what will you get?
