Answer 2

Answer:

$x$ = $\frac{-1}{2}$= -0.5

Step-by-step explanation:

($\frac{2}{7}$)7x ($\frac{2}{9}$)2=($\frac{2}{9}$)2x-1​

⇒$2x$×$\frac{4}{9}$=$\frac{4x}{9}$-$\frac{2}{9}$

⇒$\frac{8x}{9}$=$\frac{4x}{9}$-$\frac{2}{9}$

⇒$\frac{4x}{9}$=-$\frac{2}{9}$

⇒$x$ = $\frac{-2}{9}$×$\frac{9}{4}$

∴ $x$ = $\frac{-1}{2}$= -0.5
