Answer 1

a- b= 83,04
a= 7b
7b-b= 83,04
6b= 83,04
b= 83,04/6
b= 13,84

a= 7b= 7•13,84= 96,88

a-b= 83,04
96,88- 13,84= 83,04
83,04= 83,04

Answer 2

a-b=83,04

a=7b

7b-b=83,04

6b=83,04

b=83,04 / 6

b=13,84.

a=a-b+b=x

a=83,04+13,84=96,88.

7b-b=83,04

6b=83,04

b=83,04 / 6

a=a-b+b=x

a=83,04+13,84=96,88.
