Use substitution. 
y = 2 - x and y = 4x + 7 can become
2 - x = 4x + 7
Now solve for x
-5 = 5x
-1 = x
Now plug -1 for x in either equation.
y = 2 - x -> y = 2 - (-1) -> y = 3
y = 4x + 7 -> y = 4*-1 + 7 -> y = -4 + 7 -> y = 3
So C) is the correct answer.
        
             
        
        
        
The answer is C.0,3 because One of Y equal 0 for X

Kelly has $10
- half: $10 - 1/2 x $10
$10 - $5 = $5
- one third: $5 - 1/3 x $5
$5 - $1.6667... or $5 - $1 and 2/3 = $3.33... or $3 and 1/3 or $10/3
She will have left $3.33 left, or $3 and 1/3
