Answer 1

1)deimpartit = cat * impartitor +rest

d+c+i+r+143

d=3i+10

3i+10+3+10+i=143

4i=120

i=30

d=100

3) a+b=32

a:b= 3 rest 4

a=3b+4

3b+4+b=32

4b=28

b=7

a=25

8)a-b=279

a:b=5 rest 31

a=5b+31

4b=248

b=62

a=279+62=341

9)a-b=38

a=5b+2

4b=36

b=9

a=47

10)a-b=35

a:b=4 rest 2

a=4b+2

3b=33

b=11

a=46
