1/6(-y+13)
is the answer
so the third option
Answer:
1. Color Change.
2. Production of an odor.
3. Change of Temperature.
4. Evolution of a gas (formation of bubbles)
5. Precipitate (formation of a solid)
Step-by-step explanation:
the construction of fields of formal infinite series in several variables, generalizing the classical notion of formal Laurent series in one variable. Our discussion addresses the field operations for these series (addition, multiplication, and division), the composition, and includes an implicit function theorem.

Hello!
You first make two equations
Let x stand for the price of a burger
Let y stand for the price of fries
3x + 2y = 7.15
4x + 3y = 9.93
multiply the top equation by 3 and the bottom equation by 2
9x + 6y = 21.45
8x + 6y = 19.86
You can subtract the two equations
x = 1.59
Now you can put x into one of the original equations
3(1.59) + 2y = 7.15
Combine like terms
4.77 + 2y = 7.15
Subtract 4.77 from both sides
2y = 2.38
Divide both sides by 2
y = 1.19
The answers are a burger cost $1.59 and Fries cost $1.19
Hope this helps!
