(x+(x+2)+ x+4)3=x(x+2)+ 18
..
(x+x+2+x+4)3=x^2+2x+18
(3x+6)*3=x^2+2x+18
9x+18=x^2+2x+18
x^2+2x=9x
x^2= 9x-2x
x^2=7x
x= 7x/x
x=7

%28x%2B%28x%2B2%29%2B%28x%2B4%29%29%2A3=x%28x%2B2%29%2B18
%283%2Ax%2B6%29%2A3+=+x%5E2%2B2x%2B18,
9x%2B18+=+x%5E2%2B2x%2B18,
0+=+x%5E2+-7x,
0+=+x%28x-7%29,
x+=+0, or x+=+7.
