$1) x+0.52=1\\x=1-0.52\\x=0.48 \\ \\ 2) y-4.25=3.75 \\ y=3.75+4.25 \\ y=8 \\ \\ 3) 8-m=3\\m=8-3\\m=5 \\ \\$

$4) (234+x)-456=178 \\ 234+x=178+456 \\ 234+x= 634\\x=634-234\\x=400 \\ \\ 5) (x-4.83)+0.16=3.02 \\ x-4.83=3.02-0.16 \\ x-4.83=2.86 \\ x=2.86+4.83\\x=7.69 \\ \\$

$6)(8164-x)-2398=2557 \\ 8164-x=2557+2398 \\ 8164-x=4955 \\ x=3209 \\ \\ 7) 0.8-(x-0.326)=0.495 \\ x-0.326=0.8-0.495 \\ x-0.326=0.305 \\ x=0.305+0.326 \\ x=0.631$

$8) 5.2-(6-y)=3.258 \\ 6-y=5.2-3.258 \\ 6-y=1.942 \\ y=6-1.942 \\ y=4.058$
