Question

SOLVE THE EQUATION CHECK FOR EXTRANEOUS SOLUTION.
|x+5|=3x-7

Answer 1

Answer:

One answer, x = 6.

.5 or 1/2 is an extraneous solution (not a valid solution).

If you are asked specifically if there are any extraneous solutions, then you would list it as such.

I've never had a problem ask for extraneous solutions, since it's not a solution to the problem.

Answer 2

(x+5)=3x-7

x+5=3x+7

x-3x=7-5

-2x=2

X=2/2

x =1
