$-\frac{2}{3}x-\frac{2}{3}x-\frac{4}{5}y=0-\frac{4}{5}y$

$5\left(x-3\right)=5x-15$

$\frac{7}{2}x-\frac{1}{2}y+\frac{1}{2}y=\frac{7}{2}x+0$

$\left(\frac{1}{3}x+\frac{5}{4}y\right)+\frac{3}{4}y=\frac{1}{3}x+\left(\frac{5}{4}y+\frac{3}{4}y\right)$

$\left(\frac{5}{3}x+\frac{8}{5}x\right)-\frac{3}{5}x=\frac{5}{3}x+x$

$\frac{1}{4}\left(x-11\right)=\frac{1}{4}x=\frac{11}{4}$

$0.4y+\left(3.6y-0.6\right)=4y-0.6$

$\frac{4}{5}\times\frac{5}{4}x+\frac{12}{5}=x+\frac{12}{5}$

$7.8x-1.3-1.8x=6x-1.3$

$\frac{y}{0.35y}=0.65y$

$y-0.35y=0.65y$

$y+0.65y=0.35y$

$y+0.35y=0.65y$

Amanda takes out 50% of the nickels in the gar on Friday and adds a number of nickels that is equal to 30% of the remaining number of nickels in the jar on Monday. There are 20% fewer nickels in the jar after Monday than before Friday.
