Answer:
Just to recap, an equation has no solution when it results in an incorrect "equation".
For example:
Equation: x+3 = x+4
Subtract x: 3 = 4???
But clearly, 3 is not equal to 4, so this equation has NO SOLUTION.
Now onto our problem:
13y+2-2y = 10y+3-y
11y+2 = 9y+3
2y=1
y=1/2
9(3y+7)-2 = 3(-9y+9)
27y+61 = -27y+27
54y = -34
y = -34/54
32.1y+3.1+2.4y-8.2=34.5y-5.1
34.5-5.1=34.5y-5.1
5.1=5.1
infinite solutions
5(2.2y+3.4) = 5(y-2)+6y
11y+17 = 11y-10
17 = -10??
That's not true, so the option "5(2.2y+3.4) = 5(y-2)+6y" has no solution.

Explanation
Step 1
you can easily solve this by using a rule of three.
Let
x represents the money Eileen will pay if her bag weighs 63 pounds
the proportion is the same
then
![\frac{7.14}{42}=\frac{x}{63}](https://tex.z-dn.net/?f=%5Cfrac%7B7.14%7D%7B42%7D%3D%5Cfrac%7Bx%7D%7B63%7D)
Step 2
solve for x
![\begin{gathered} \frac{7.14}{42}=\frac{x}{63} \\ 63\cdot7.14=42x \\ x=\frac{63\cdot7.14}{42} \\ x=\frac{449.82}{42} \\ x=10.71 \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B7.14%7D%7B42%7D%3D%5Cfrac%7Bx%7D%7B63%7D%20%5C%5C%2063%5Ccdot7.14%3D42x%20%5C%5C%20x%3D%5Cfrac%7B63%5Ccdot7.14%7D%7B42%7D%20%5C%5C%20x%3D%5Cfrac%7B449.82%7D%7B42%7D%20%5C%5C%20x%3D10.71%20%5C%5C%20%20%5Cend%7Bgathered%7D)
