Answer 1

м+(п-к)=м+п-к
с-(-а-в)=с+а+в
(-2)(х+у-8)=-2х-2у+16
(-3)(-х+у+12)=3х-3у-36

3,3(х-6.7)=100
3.3х-22,11=100
3.3х=122,11
х=122.11:3.3
х=37.00303

4-57-(м-1)=11/14
4-57-м+1=1114
-м=1114-4+57-1
-м=11/14-4*!4/14+5*214-14/14
-м=-41/14
м=2 13/14

-1.3+(х-4.8)=-7.1
-1.3+х-4.8=-7.1
х=-7.1+1.3+4.8
х=-1

1 56-(у+23)=1 12
-у=32-11/6+23=3*3/6-116+2*26
-у=2
у=-2
