Roger has two golden retrievers, sadie and buddy, buddy weighs 14 pounds more than sadie, if their total wight is 136 pounds, how much does sadie weigh

If their total weight is 136 pounds, sadie weigh 61 pounds.

Let the weight of Sadie=x

Let the weight of Buddy=y

Hence:

y=x+14

Total weight= x +y=136 pounds

Formulate

14+2×x=136

x+x+14=136

2x=136-14

2x=122

Divide both side by 2x

x=122/2

x=61 pounds

Inconclusion If their total weight is 136 pounds, sadie weigh 61 pounds.
