Question

How can I find out if an equation has no answer, has infinite answers has one answer or has 2 answers?

Answer 1

@dude

Answer 2

just a general question

Answer 3

Well if an equation has infinite solutions it is the same equation written in a different way
2(x+2)=2x+4 (infinite solutions)

If 2 lines are parallel, or have the same coefficient they have no solutions
\(x+7= x+4\)

Answer 4

Oh okay

Answer 5

So if they have 2 solutions, i have to go through looking for the second one?

Answer 6

Parabolas usually have 2 solutions

But can it be like this? 2 + 3x = 2 + 3x?

Answer 10

what if it is the same equation?

Answer 11

Yep, if it is the same equation it has infinite solutions

Answer 12

oh okay

Answer 13

thx

Answer 14

:D

Answer 15

No problem :)

Answer 16

wait

Answer 17

so an equation like y = 5x + 10 y = 5x + 2 would this be no solution?

Answer 18

sorry let me re-write that

Answer 19

Equation A:y = 5x + 10
Equation B: y = 5x + 2

Answer 20

@dude

Answer 21

Answer 22

so it would have no solution?

Answer 23

Correct

Answer 24

ok

Answer 25
