Let y represent Tim's age and let x represent Chris's age.
y=3x
y=x+14
Set the two equations equal to each other:
3x=x+14
Subtract the x from the one side to get it on the other side.
2x=14
Divide by 2 on both sides
14/2=7
x=7
Plug it back in and see if it works:
y=3(7)=21
Other equation:
7+14=21
x=7
y=21
$85.20/6= $14.20/pair is the answer because unit price equals cost/pairs

Answer:
C
Step-by-step explanation:
The wanted region(shaded part)..is greater or equal to 2 due to the bold line...so hence the first inequality is....y is greater than or equal to 2
And the second solution....is y is less than x because of the continuous broken line...hence it cant be less than or equal to
