Question

Solve:
2x-1 = 3
x-1 x+3

Answer 1

hmmm, I can't really make out the equation(s) here. what are the x-1 and x+3 for?

Answer 2

i think its soppused to be like 2x-1 over x -1 and 3 over x+3

Answer 3

oh, ok, gotcha
so you need a common denominator. let's put everything on the same side
(2x-1)/(x-1) - 3/(x+3)=0
to get the common dnominator,
((2x-1)*(x+3))/((x-1)*(x+3)) - 3*(x-1)/((x+3)*(x-1)
((2x^2+2x-3) - (3x-3))/(x^2+2x-3)
(2x^2-x)/(x^2+2x-3)
I'll catch my breath now

Answer 4

@brook aint that simulataneous equation

Answer 5

oups, made a mistake here

Answer 6

it's ((2x^2+5x-3) - (3x-3))/(x^2+2x-3)
then (2x^2+2x)/(x^2+2x-3)

Answer 7

I get the feeling I did something wrong here... @razor99 got an idea?

Answer 8

oh, no, ok, got it...
since that equation equals 0, you can scratch the denominator, leaving you with :
2x^2+2x = 0
x^2+x = 0
x^2 = -x
x = -1

when you plug it back in, it works, so that's fine by me. May have been unnecessarely long, but I got there ;-)

Answer 9

no guyz 3 would be the answer

Answer 10

2*3/2 doesn't equal 3/(3+3), unless I'm missing something?
