Question

What does a common solution mean in algebra 2?? please help?

Answer 1

@Calcmathlete can you please help me??

Answer 2

Well, what's the problem this is from?

Answer 3

Otherwise though, a common solution means same solution.

Answer 4

THis also means that they share the solution.

Answer 5

It varies on the problem and the context.

Answer 6

can i show you the problem??

Answer 7

Which pair of equations does NOT have a common solution?
A) x + y = -14x - 3y = 24
B) 4x + 6y = 12 6x + 9y = 12
C) 2x - 3y = -4 2x + y = 4
D) 5x - 4y = 9 x - 2y = -3..
if you can solve this an explain your answer this would BE VERYYYYY HELPFUL

Answer 8

Are you familiar with the cases of no solution and infinitely many solutions, 0 = 0, 0 = 6 respectively?

Answer 9

a little bit.. don't remember it...

Answer 10

Well, in some cases, the variable will disappear. If you are left with a situation like this:
0 = 0 or 6 = 6, then you have infinitely many solutions meaning that it's the sme line. If you have a case that's like 0 = 4 or 5 = 7, then you have a case of no solution in which they re parallel lines and therefore never intersect. Set up a system of equations for each choice and see which one comes out like 0 = 4 or 5 = 2, etc.

Answer 11

oh so i this case it has to be a common solution would have to be 0=0? ???

Answer 12

We're looking for the case in which it's NO SOLUTION. this means that the variable has to disappear and the numbers have to be different. See how the numbers are different?: 4 = 7

Answer 13

ohhhhh yeah! okay thanks :) i see now,. you explained that great!! :D

Answer 14

No Problem :)

Answer 15

-7/8=8/7 does that give us our answer.. thats what i ended up with on the first one A...
