1) 80+32(80*0,4)=112 2)80-32=48
Решение
x = 24
x - 6 = 24 - 6 = 18
x/6 = 24/6 = 4
x = 36
x - 6 = 36 - 6 = 30
x/6 = 36/6 = 6
x = 42
x - 6 = 36
x/6 = 42/6 = 7
x = 180
x - 6 = 180 - 6 = 174
x/6 = 180/6 = 30
x = 240
x - 6 = 240 - 6 = 234
x/6 = 240/6 = 40
35/4 - 47/6=11/12
3,6+4,8 * (8 3/4 - 7 5/6 )=3.6+48/10*11/12=3.6+3.4=8
5=36,7=42,4=33,9=8,11=16,13=24,15=32.
