Question

x+1/3x=12

Answer 1

x+1/3x=12 *I assume you mean (x+1)/3x = 12
x+1 = 36x
1 = 35x
1/35 = x

Answer 2

\[x+\frac{1}{3x}=12\]
\[\frac{3x^2+1}{3x}=12\]
\[3x^2+1=36x\]
\[3x^2-16x=-1\]
\[(1\sqrt{3}x^2)-(4\sqrt{x})^2=-1\]
\[(\sqrt{3}x-4\sqrt{x})(\sqrt{3}x+4\sqrt{x})\]

Answer 3

X is equal to 3.5 i think

Answer 4

x+1/3x=12 |*x
\[x^2+\frac{1}{3}=12x\]
can multiply both sides with 3 and get
\[3x^2-36x+1=0\]
And solve it.

Answer 5

I suppose you could be looking at x + 1/3 x = 12
4/3 x = 12
x = 9

Answer 6

no I meant x + one-thirdx=12. Can u please do this problem again?

Answer 7

TBates go to chat!!!! plz!!!

Answer 8

So it is x + (1/3) x = 12? If so then my last post has the worked out solution

Answer 9

arthurfan i did it see above

Answer 10

3/3x+1/3x=12
4/3x=12
x=12*3/4
x=9
