✔ 最佳答案
ur question seems to be difficult to understand....is it 3x^4 ?????
i think so....
if it is that then
3x^4 = x/4
3x^3 = 1/4
x^3 = 1/12
x = (1/12)^(1/3)
answer
or if it is 3*4 = 12 then
12 = 1/4 x
= > x = 48 answer

3x+4=1/4x
3x+4(4)=1/4x(4)
4(3x+4)=x
12x+16=x
3x+4(4)=1/4x(4)
4(3x+4)=x
12x+16=x

(3x)(4) = 1/4(x)
12x = x/4
12x - x/4 = 0
x(12 - 1/4) = 0
x = 0
12x = x/4
12x - x/4 = 0
x(12 - 1/4) = 0
x = 0

3*4 = x/4
12 = x/4
x= 48
12 = x/4
x= 48

oh I used to get stuck on these all the time!
okay first u need to multiply 3 x 4.
3 x 4 = 1/4 x
12 = 1/4 x
then u need to get x alone.. so u divide 1/4 from either side
12 = 1/4 x
12 divided by 1/4 = .25
1/4 divided by 1/4. you cross cancel so it equals 0.
then I think u multiply
12 x .25 = x
48 = x

If you had a quarter of anything you would know that something had been cut into 4 pieces
To make x into a whole you will have to multiply by 4
to give 1/4 times 4 makes 1x
You can do this with an equation as long as you multiply everything in the equation by 4 to keep a balance (like weighing scales)
So your sum 12 = 1/4x will become 48 = x
So x = 48

48x^2=1
x^2=1/48
x= + & - 0.14433
x^2=1/48
x= + & - 0.14433

Well
3 X 4= 12 right, but the answer is a quarter times X so you multiply 12 by 4 which equals 48
so 3 X 4 = 1/4 X 48

3x4 = 1/4x
12 = 1/4x
cross multiply,
x=48
12 = 1/4x
cross multiply,
x=48

there is a bit of ambiguity in your question
im not too sure what 3x 4 is
perhaps you omitted a /
1/4 x is also ambiguous, as it can imply 1/(4x) or (1/4)x
but if the equation was 3x / 4 = (1/4)x
-cross multiply
=> 3x / 4 = x / 4
=> 3x*4 = 4x
=> 12x = 4x
=> 8x = 0
x = 0
or if the equation was (3x)4 = (1/4)x
=> 12x = x / 4
=> 48x = x
=> 47x = 0
x = 0
or if the equation was (3x)4 = 1/(4x)
=> 12x = 1(4x)
=> 48x^2 = 1
x = 1 / 48
x = + or - 1/ [sqrt(48)]
x = + or - 1 / [4sqrt (3)]
or if the equation was 3x / 4 = 1/(4x)
=> 12x^2 = 4
=> x^2 = 1 / 3
=> x = + or - 1/sqrt(3)
sorry i cant really help much because your equation is a bit ambiguous
