Answer:
52 32- cent stamps and 26 13-cent stamps
Step-by-step explanation:
Let x be the 32-cent stamps and y be the 13-cent stamps then...
x=2y
32x+13y=2002 (note that $20.02 is 2002 cents)
We can solve using substitution (substitute 2y for x)
32(2y)+13y=2002
64y+13y=2002
77y=2002
y=26
x=2(26)
x=52

Step-by-step explanation:
Answer:x=328
solution=<span> (4x-16)^1/2=36
squaring both sides we get
4x-16=1296
4x=1296+16
x=(1296+16)/4
x=328 .</span>
