[tex] \frac{2}{3( \frac{x+1}{2})+ \frac{1}{3} } = \frac{5}{6} [/tex]
[tex] \frac{2}{ \frac{3x+3}{2} + \frac{1}{3}= \frac{5}{6} } [/tex]
3*[tex] \frac{3x+3}{2} [/tex]+2*[tex] \frac{1}{3} [/tex]=[tex] \frac{9x+9+2}{6} = \frac{9x+11}{6} [/tex]
12=[tex] \frac{45x+55}{6} [/tex]
45x+55=12*6
45x+55=72
45x=72-55
45x=17
x=[tex] \frac{17}{45} [/tex]
