Answer:

ǫᴜᴇsᴛɪᴏɴ

Solve :-

\small \bf x =  \dfrac{x + 1}{5}  -  \dfrac{x - 2}{4}

ANSWER★

\small \bf x =  \dfrac{x + 1}{5}  -  \dfrac{x - 2}{4}

On taking LCM on RHS, we get

\small \bf x \:  =  \dfrac{4(x + 1) - 5(x - 2)}{20}

\bf \implies \: \: x \:  =  \dfrac{4x + 4 - 5x + 10}{20}

\bf \implies \:x =  \dfrac{14 - x}{20}

\bf \implies \: \: 20x = 14 - x

On transposing

\bf \implies \:20x + x = 14

\bf \implies \:21x = 14

\bf \implies \:x =  \dfrac{14}{21}  =  \dfrac{2}{3}

\underline{\boxed{\sf Verification}}

Consider RHS

\small \bf  \dfrac{x + 1}{5}  -  \dfrac{x - 2}{4}

\small \bf  ⟹\dfrac{ \dfrac{2}{3} + 1 }{5}  - \dfrac{ \dfrac{2}{3}  - 2}{4}

\bf \implies \:  \dfrac{2 + 3}{3 \times 5} -  \dfrac{2 - 6}{3 \times 4}

\bf \implies \: \dfrac{1}{3}  -  \dfrac{( - 1)}{3}

\bf \implies \: \dfrac{1}{3}  + \dfrac{1}{3}

\bf \implies \: \dfrac{2}{3}

\bf \implies \:LHS
