answer .......

Answer 2

Given

$\implies\sf 12-\frac{2}{3}(2x-5)+3x=5$

To find

Find the value of x

Solution

$\implies\sf 12-\frac{2}{3}(2x-5)+3x=5 \\ \\ \implies\sf \frac{-2(2x-5)+9x}{3}=5-12 \\ \\ \implies\sf \frac{-4x+10+9x}{3}=-7 \\ \\ \implies\sf 5x+10=-21 \\ \\ \implies\sf 5x=-21-10 \\ \\ \implies\sf 5x=-31 \\ \\ \implies\sf x=\frac{-31}{5}$

Verification

$\implies\sf 12-\frac{2}{3}(2x-5)+3x=5$

Putting the value of x

LHS

$\implies\sf 12-\frac{2}{3}(2x-5)+3x \\ \\ \implies\sf 12-\frac{2}{3}(2\times\frac{(-31)}{5})+3\times\frac{(-31)}{5} \\ \\ \implies\sf 12-\frac{2}{3}(\frac{-62}{5}-5)+\frac{(-93)}{5} \\ \\ \implies\sf 12-\frac{2}{3}(\frac{-62-25}{5})-\frac{93}{5} \\ \\ \implies\sf 12+\frac{2}{3}\times\frac{87}{5}-\frac{93}{5} \\ \\ \implies\sf 12+\frac{174}{15}-\frac{93}{5} \\ \\ \implies\sf \frac{180+174-279}{15} \\ \\ \implies\sf \frac{75}{15}$

$\implies\sf 5$ = RHS verified
