D=dog's weight
c=cat's weight
d=7c
d+c=72
sub 7c for d
7c+c=72
8c=72
divide both sides by 8
c=9
d=7c
d=7(9)
d=63
dog=63lb
We are doing this rn the answer is in the box
In order to find the value for 'w', you will need to cancel out -4w by adding 4w from the right side to the left side. You will have a equation of 4w=-28, but you will also need to have 'w' by itself so you will divide -28 to 4. Your final answer is -7.

7-2 is 5
20 divided by 5 is 4
4 times 2 is 8
4 times 7 is 28
28 add 8 is 36
