Question 196761: Solve each equation. Check each solution.
1. -x/4=2x/3
I got x=-5 and it is extraneous.
2.2x-4/x-5=0
I got x=-1 and it is extraneous.
Could someone please check these?
Thank you!

You can put this solution on YOUR website!
(1) -x/4 =2x/3
cross multiply
8x =-3x
11x=0
x=0
.
(2) (2x-4) / (x-5) =0
cross multiply
2x-4 =0
2x=4
x=2
.
Extraneous Solutions usually come about when we square something, and bring in
positive or negatives that do not apply
.
to define extraneous, check all answers and those that do not satisfy original
statements are extraneous.
