SOLUTION: My question is
2 + √3x = x/3
Show far I have worked out.
Multiply both sides by 3
3(2 + √3x) = x
Then expanded bracket out
6 + 3√3x = x

Show far I have worked out.
Multiply both sides by 3

Don't no if I have done correct so far and what to do next.
Any help would be gratefully recieved.

My question is
2 + √3x = x/3
Show far I have worked out.
Multiply both sides by 3
3(2 + √3x) = x
Then expanded bracket out
6 + 3√3x = x
That's right so far, continuing
:
subtract 6 from both sides
= x - 6
:
Square both sides
9(3x) = (x-6)^2
27x = x^2 - 12x + 36
:
A quadratic equation
x^2 - 12x - 27x + 36 = 0
x^2 - 39x + 36 = 0
:
This equation requires the quadratic formula
:
In this problem; a=1; b=-39; c=36
:
:
Two solutions
x =
x = 38.054
and
x =
x = .946
:
:
Check both solutions in original equation, only x=38.054 is a valid solution
