amorfide · Answer

if you look closely, you see that if you multiply equation 1 by 2 that it becomes the same line as equation 2
therefore you have infinite solutions

anonymous · Answer

Solve the linear system.
x + y = -3
y = 2x

(-1, -2)
no solution
coincident

ribhu · Answer

sorry coincident

anonymous · Answer

What about this one?

ribhu · Answer

coincident

anonymous · Answer

Both answers are coincident?

ribhu · Answer

last one one solution, this one coincident

anonymous · Answer

Thought you said no solution?

ribhu · Answer

did i? wait

ribhu · Answer

one solution for first and coincident for this one

anonymous · Answer

x + y = 6
x - y = 8
Solve the system of equations.

(1, -7)
(7, -1)
no solution

anonymous · Answer

???

anonymous · Answer

The first one has infinite solutions, because it comes out to be 0 = 0

The second one has one solution, (-1, -2) Solved by substitution.

Your third one is substitution again, one solution, (7,-1)

Please ask any questions if you're not sure how I got those answers.

anonymous · Answer

@Kommander_Kitten But infinite solutions isn't one of the answer choices?
