Hey! I said I'm here to help! :)
One batch = 3 3/4 + 1 5/8
one batch = 3 6/8 + 1 5/8
one batch = 4 11/8
one batch = 5 3/8 pound of flour
One week = 86 pound
86 ÷ 5 3/8 = 86 ÷ 43/8
86 ÷ 5 3/8 = 86 x 8/43
86 ÷ 5 3/8 =16

You have the polynomial .
The additive inverse of a polynomial f(x,y) is a polynomial that makes zero when it added to polynomial f(x,y). So additive inverse of polynomial f(x,y) will be -f(x,y).
Thus, the additive inverse will be
.
Substitution, elimination, and graphing.
