System of Equations Sample Post
At a dog park, there were a total of 18 dogs and people combined. There were a total of 50 legs on the dogs and people. How many dogs and people were at the park?
Let d = number of dogs at the park; then 4d = total number of legs on the dogs.
Let p = number of people at the park; then 2p = total number of legs on the people.
Equation 1: The total number of dogs and people at the park is 18: d + p = 18
Equation 2: The total number of legs at the park is 50: 4d + 2p = 50
Use substitution to solve the system of equations.
Solve Equation 1 for p by subtracting d from each side: p = 18 – d
Substitute 18 – d for p in Equation 2 and then solve for d:
4d + 2(18 – d) = 50
4d + 36 – 2d = 50 distribute on the left side
2d + 36 = 50 combine like terms on the left side
2d = 14 subtract 36 from each side
d = 7 divide both sides by 2
If d = 7, then p = 18 – 7 = 11.
Check number of legs: 4(7) + 2(11) = 28 + 22 = 50.
So there were seven dogs and eleven people at the park.
