Oranges = x dollars
apples = x+3 dollars
An equation is
Oranges + Apples = 10 dollars, or
x + (x+3) = 10
2x = 10-3
2x = 7
x = 7/2 = 3.5

Answer:
and 
Step-by-step explanation:
The first answer you are just adding 4 and 1/4. The second answer you are adding a negative number with a postive fraction so you get a negative fraction.
Area=legnth times width
width=2/3 legnth
w=2/3l
a=lw
subsitute
a=l(2/3l)
a=864
864=2/3l^2
multiply both sides by 3/2 to clear fraction
2592/2=l^2
1296=l^2
square root both sides
36=legnth
width=2/3 legnth
width=2/3 times 36
width=72/3=24
legnth =36 feet
width=24 feet
