Let x = number of long sleeve shirts
Let y = number of short sleeve shirts
x + y = 200
x/2 + y/3 = 80
Now solve this pair of simultaneous equations to find x and y.
X = y + 5
-y + x - x = y - y + x + 5
-y = x + 5
y = x - 5

Answer: Choice A is correct.</h3>
The degree is the largest exponent of a single variable polynomial.
Answer:
B
Step-by-step explanation:
In order for something to have infinite solutions, both sides need to be equal to each other.
Example:
3x + 7y = 7y + 3x
That has infinite solutions
3x + 7y = 7x + 3y
That is not equal to each other because the variables are different.
Hope I helped :)
