Y-1/5=3/5. 1-x= 7/13. x+ 5/11=1. 1-y= 9/17. x+ 3/100= 1

1)
$y - \frac{1}{5} = \frac{3}{5} \\ y = \frac{3}{5} + \frac{1}{5} \\ y = \frac{4}{5}$

2)
$1 - x = \frac{7}{13} \\ x = 1 - \frac{7}{13} \\ x = \frac{6}{13}$

3)
$x + \frac{5}{11} = 1 \\ x = 1 - \frac{5}{11} \\ x = \frac{7}{11}$

4)
$1 - y = \frac{9}{17} \\ y = 1 - \frac{9}{17} \\ y = \frac{8}{17}$

5)
$x + \frac{3}{100} = 1 \\ x = 1 - \frac{3}{100} \\ x = \frac{97}{100}$
