Question :-

\large\bf\red{2x -  \frac{3}{2}  +  \frac{2}{3}  = 2}

\huge\underline\textsf{Explantion:- }

\bf\rightarrow\frac{4x - 3}{2}  + \frac{9x - 2}{3}   = 2 \\  \\\bf\rightarrow\frac{3(4x - 3) + 2(9x - 2)}{6}  = 2 \\ \\ \bf\rightarrow\frac{12 \times  - 9 + 18x - 4}{6}  = 2

 \bf\rightarrow\frac{30x - 13}{6}  = 2 \\ \\ \bf\rightarrow30 x - 13 = 12 \\ \\\bf\rightarrow  30x = 13 = 12

\bf\rightarrow30x  = 12 + 3 \\ \\\bf\rightarrow30x = 25 \\ \bf\rightarrow x =  \frac{\cancel2\cancel5}{\cancel3\cancel0}

\large\bf \rightarrow\frac{5}{6}

\huge\underline\textsf{Verification:- }

\bf\rightarrow L.H.S = 2x -  \frac{3}{2}  + 3x -  \frac{2}{3}

\sf \rightarrow2 \times ( \frac{5}{6} ) -  \frac{3}{2}  + 3 \times ( \frac{5}{6} ) -  \frac{2}{3}

\sf \rightarrow\red{\frac{5}{3}  -   \frac {3}{2} +  \frac{5}{2}   -  \frac{2}{3 } }

\sf\rightarrow(\frac{10 - 9}{6} ) +  (\frac{15 - 4}{6} )

\sf \frac{1}{6}  +  \frac{11}{6 }  \\   \\ \bf\rightarrow\frac{\cancel1\cancel2}{\cancel6}

\large\bf \rightarrow\green{2 =  \: R.H.S}

L. H. S = R. H. S
