A=stay in Australia; J=stay in Japan=A+4wks; S=stay in Sweden=A-3wks
A+J+S=37 weeks Substitute for J and S, solve for A.
A+(A+4wks)+(A-3wks)=37wks
3A+1wk=37wks Subtract 1 wk from each side.
3A=36wks Divide each side by 3.
A=12wks ANSWER 1: They will spend 12 weeks in Australia.
J=A+4wks=12wks+4wks=16wks ANSWER 2: They will spend 16 weeks in Japan.
S=A-3wks=12wks-3wks=9wks ANSWER 3: They will spend 9 weeks in Sweden
CHECK:
A+J+S=37 weeks
12 weeks+16 weeks+9weeks=37 weeks
37 weeks=37 weeks

Japan+%2BAustralia%2BSweden=37
let the number of weeks in Australia be x
if they stay in Japan for 4 more weeks than they will be in Australia, then Japan will be Japan=x%2B4
if their stay in Sweden will be 3 weeks shorter than that in Australia, then their stay in Sweden will be Sweden+=x-3
plug it in Japan+%2BAustralia%2BSweden=37
%28x%2B4%29%2Bx%2B%28x-3%29=37..........solve for x
x%2B4%2Bx%2Bx-3=37
3x%2B1=37
3x=37-1
3x=36
x=36%2F3
highlight%28x=12%29
highlight%28Australia+=12%29->the number of weeks in Australia
Japan=x%2B4
Japan=12%2B4
highlight%28Japan=16%29->the number of weeks in Japan
Sweden+=x-3
Sweden+=12-3
highlight%28Sweden+=9%29->the number of weeks in Sweden
