create a system of equations:
4 y + 2 x = 34
y + x = 10
* y is for buffaos and x is for ducks
solve the equation:
y=10-x
4(10-x)+2x=34
x=3
y=10-3
y=7

Use Order of Operations!! Remember PEMDAS!
P: Parentheses first
E: Exponents (ie Powers and Square Roots, etc.)
MD: Multiplication and Division (left-to-right)
AS: Addition and Subtraction (left-to-right)
7+25•4 (multiply 25 by 4 first)
7+100 (then add 7 to 100)
107
So your final answer would be 107
