Final answer:
There are 14 dogs and 46 chickens on your uncle's farm.
Step-by-step explanation:
To solve this problem, we can set up a system of equations. Let x be the number of dogs and y be the number of chickens on your uncle's farm.
The number of legs equation can be written as: 4x + 2y = 148 (since dogs have 4 legs and chickens have 2 legs).
The number of heads equation can be written as: x + y = 60 (since both dogs and chickens have 1 head).
We can solve this system of equations by substitution or elimination. Let's use elimination:
Multiplying the second equation by 2, we get 2x + 2y = 120.
Subtracting the new equation from the first equation, we can eliminate the 2y term: (4x + 2y) - (2x + 2y) = 148 - 120. Simplifying, we have 2x = 28.
Dividing both sides of the equation by 2, we find that x = 14. Substituting this value back into the second equation, we find that 14 + y = 60. Solving for y, we get y = 46.
Therefore, there are 14 dogs and 46 chickens on your uncle's farm.
