Answer:
weight of legs - 7 ounces
weight of wings - 4 ounces
Step-by-step explanation:
Let the weight of a chicken leg be represented by l
Let the weight of a chicken wing be represented by w
The total weight of Mr. Nguyen's package can be represented by this equation :
4l + 6w = 52
The total weight of Ms. Dawen's package can be represented by this equation :
3l + 6w = 45
To find the weight of the legs and wing, use simultaneous equation
4l + 6w = 52 eqn 1
3l + 6w = 45 eqn 2
Subtract equation 2 from 1
l = 7 ounces
Substitute for l in equation 1
4(7) + 6w = 52
28 + 6w = 52
Solve for w
w = 4 ounces
