Answer:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
Step-by-step explanation:
First calculate the value of the 3 shirts as follows:
$ 71.83 - $ 7.99 = $ 63.84.
$ 63.84.
The general equation would be, where x is the value of shirt # 1, and the value of shirt # 2 and z is the value of shirt # 3:
x + y + z = 63.84, then for each shirt would be the following equations:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
For example, if we give values (always the sum of both under 63.84) to two shirts, x = $ 20, y = $ 30 then the value of shirt # 3 would be:
<em>z = 63.84 - 20 - 30 = $ 13.84</em>

Answer:
8x - 8y
Step-by-step explanation:
3(x - y) is equal to 3x - 3y using distributive property
The same applies to 5(x - y) which is equal to 5x - 5y
Combine like terms in (3x - 3y) + (5x - 5y) which is equal to 3x + 5x + 3y + 5y
Final Answer is 8x - 8y
