the weight of abes dog can be found using the expression 2(x+3), where x is the number of weeks. the weight of karens dog can be

ivanzaharov [21]

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

$\sf 2(x+3)=3(x+1)$

Solve for 'x', first distribute:

$\sf 2x+6=3x+3$

Subtract 3 to both sides:

$\sf 2x+3=3x$

Subtract 2x to both sides:

$\boxed{\sf x=3}$

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

vovikov84 [41]

Answer:

y = - 6

Step-by-step explanation: You have to substitute 2 for x in order for you to get your solution.

y = - 4x + 2

y = - 4(2) + 2

y = - 8 + 2

y = - 6

Remember, a negative times a positive, becomes a negative
