Question

Please help me! this problem is algebra

Answer 1

Australia = 12

Japan = 16

Sweden = 10

Total = 38

Explanation:

A=x

J=x+4

S=x-2

Add expressions & combine like terms

x+x+4+x-2 = 38

Get rid of left constant

3x + 2 = 38

-2

3x = 36

36/3x = 12

12 = Australia

12 + 4 = 16 = Japan

12 - 2 = 10 = Sweden

Answer 2

Sweden 10 weeks

Australia 12 weeks

Japan 16 weeks

Explanation:

First establish some variables:

x will be our time in Australia

x - 2 will be our time in Sweden

x + 4 will be our time in Japan

Now we can build our equation:

x + x - 2 + x + 4 = 38

Now we can gather like terms:

3x + 2 = 38

Now subtract two from both sides of the equation

3x + 2 - 2 = 38 - 2

3x = 36

Now we divide both sides of the equation by 3 to get our answer:

`(3x)/(3) = (36)/(3)`

this results in our answer of:

x = 12

Now we put the value for x back into our variables to get the answers provided above.
