[(1000-x)/x]*2=0.06
so
[(1000-x)/x] = 0.06/2
[(1000-x)/x] = 0.03
but how can i find the x?
Thanks.

[(1000-x)/x]*2=0.06
(1000 - x)/x = 0.06/2 = 0.03
1000 - x = 0.03x
1000 = 0.03x + x
1.03x = 1000
x = 1000/1.03 = 970.873

Starting from your last line of working, multiply both sides by x:
(1000-x)/x *x = 0.03*x
1000 - x = 0.03x then add x to both sides
1000 = 0.03x + x
1000 = 1.03x then divide both sides by 1.03
1000/1.03 = x and work it out!

You're almost there. Here's how to proceed:
(1000-x) / x = 0.03
Multiply both sides by x:
1000-x = 0.03*x
Add x to both sides:
1000 = 0.03*x + x
Simplify the right side. Treat x as if it were "1x":
1000 = 0.03*x + 1x
1000 = 1.03*x
Divide both sides by 1.03:
1000/1.03 = x
970.87 = x

[(1000-x)/x] = 0.03 ............. multiply both sides by x
(1000-x) = 0.03*x
1000 - 1.03x = 0
1000 = 1.03x
x = 1000 / 1.03
x = 970.9
now, does this work in the initial eqn?
[(1000-x)/x]*2=0.06
[(1000-970.9)/970.9 ]*2=0.06
[29.12 / 970.9 ] * 2 = 0.06
[ 0.03 ] * 2 = 0.06
looks ok

1000 - x =0.03x
1000 =0.03x+x
1000 =1.03x
x =1000/1.03
x=970.8737
should help u.

1000/x-x/x=0.03,
1000/x=1.03,
x=1000/1.03,
x=970.87

continue like this:
..............
1000-x= 0.03x
1000= 1.03 x
x= 970.87 thanks for asking
