{ \qquad\qquad\huge\underline{{\sf Answer}}}

Here we go ~

\qquad \sf  \dashrightarrow \:  \cfrac{9 {}^{(x + 1)}  - 3 {}^{2x} }{4 \times 3 {}^{(2x - 1)} }

\qquad \sf  \dashrightarrow \:  \cfrac{3{}^{2(x + 1)}  - 3 {}^{2x} }{4 \times 3 {}^{(2x - 1)} }

\qquad \sf  \dashrightarrow \:  \cfrac{3{}^{(2x + 2)}  - 3 {}^{2x} }{4 \times 3 {}^{(2x - 1)} }

here :

  • { \sf {3}^{(2x+2)}=({3}^{2x - 1})\sdot (3³)}

  • { \sf {3}^{(2x)}=({3}^{(2x - 1)})\sdot (3¹)}

\qquad \sf  \dashrightarrow \:  \cfrac{3{}^{(2x  - 1)}(3 {}^{3}   - 3 {}^{1}) }{4 \times 3 {}^{(2x - 1)} }

[ taking { \sf {3}^{(2x - 1)} }common here ]

\qquad \sf  \dashrightarrow \:  \cfrac{27 {}^{}   - 3 {}^{}}{4  }

\qquad \sf  \dashrightarrow \:  \cfrac{24{}^{}   {}^{}}{4  }

\qquad \sf  \dashrightarrow \: 6

\dfrac{2m}{5}+3=7(4m-3)\ \ \ \ |use\ distributive\ property:a(b-c)=ab-ac\\\\\dfrac{2m}{5}+3=28m-21\ \ \ \ \ |multiply\ both\ sides\ by\ 5\\\\2m+15=140m-105\ \ \ \ |subtract\ 140m\ from\ both\ sides\\\\-138m+15=-105\ \ \ \ |subtract\ 15\ from\ both\ sides\\\\-138m=-120\ \ \ \ |divide\ both\ sides\ by\ (-138)\\\\m=\dfrac{120:6}{138:6}\\\\\boxed{m=\frac{20}{23}}
