To find this out we can set the expressions equal to each other:

[tex]\sf 2(x+3)=3(x+1)[/tex]

Solve for 'x', first distribute:

[tex]\sf 2x+6=3x+3[/tex]

Subtract 3 to both sides:

[tex]\sf 2x+3=3x[/tex]

Subtract 2x to both sides:

[tex]\boxed{\sf x=3}[/tex]

So the answer is yes, after 3 weeks the dogs will be the same weight(because 'x' represents # of weeks).
