check my answer

OpenStudy (anonymous):

Solve 5 over x plus 8 equals 3 over x for x and determine if the solution is extraneous or not. x = 12, non-extraneous x = 12, extraneous x = -12, non-extraneous x = -12, non-extraneous

OpenStudy (anonymous):

i think x = 12 but idk if its extraneous or not

@timo86m

Nnesha (nnesha):

substitute x value into original question to check if it's an extraneous or not if both sides are equal then nope if both sides are not equal then yes it's an extraneous

OpenStudy (anonymous):

can u write it down ?

OpenStudy (anonymous):

okay @Nnesha and yeah give me a sec @timo86m

OpenStudy (anonymous):

\[\frac{ 5 }{ x + 8 } = \frac{ 3 }{ x }\]

OpenStudy (anonymous):

okay now im gonna plug it in

OpenStudy (anonymous):

and yes they equal each other

OpenStudy (anonymous):

so the answer is x = 12 not extraneous

Nnesha (nnesha):
