1. `x-5/4 = 7/10`

   `x=7/10 + 5/4`

   `x=39/20`

   .

   `x-25/16=5/64`

   `x=5/64+25/16`

   `x=105/64`

   .

   `x-9/8=5/16`

   `x=5/16+9/8`

   `x=23/16`

   .

   `x-3/4=4/5+1/3`

   `x-3/4=17/15`

   `x=17/15+3/4`

   `x=113/60`

   .

   `x-3/5=5/9+5/3`

   `x-3/5=20/9`

   `x=20/9+3/5`

   `x=127/45`
