Rover weighs 5 pounds more than the neighbor’s dog. rover is 7 years old, and the neighbor’s dog is 9 years old. together they weigh 75 pounds. how much dose rover weigh

Weight of Rover is 40 pounds

Let "r" be the weight of Rover

Let "n" be the weight of nieghbour dog

Given that Rover weighs 5 pounds more than the neighbor’s dog

From this information, we can frame a equation as:

Weight of Rover = 5 + weight of Neighbour dog

r = 5 + n   eqn 1

Also given that together they weigh 75 pounds

From this information, we can frame a equation as:

Weight of Rover + weight of Neighbour dog = 75

r + n = 75 eqn 2

Let us solve eqn 1 and eqn 2 to find the values of "r" and "n"

Substitute eqn 1 in eqn 2

5 + n + n = 75

5 + 2n = 75

2n = 70

Substitute n = 35 in eqn 1

r = 5 + n = 5 + 35 = 40

Thus the weight of Rover is 40 pounds
