Answer:
The answer is "
"
Step-by-step explanation:
That's why the answer is 
For the answer to the two questions above,
3x + 2y = 36.50 (I)
2x + 5y = 50 (II)
Eliminating x from the two equations by subtraction:
first we multiply equation I by 2 and equation II by 3
6x + 4y = 73
6x + 15y = 150
Subtracting the two,
-11y = -77
y = 7
He earns $7 at the coffee cart
Substituting y into equation I,
3x + 14 = 36.5
x = $7.50
So we can conclude that, he earns a greater wage of $7.50 at the library,
I'm not sure what your statement is.
Is it x+y = 10?
Because if it is, the negation of this statement would simply be x+y<span>≠10, which stands for not equal. </span>
