**Answer:**

x=2

**Step-by-step explanation:**

Step 1_ −(x−6)=4

−x+6=4(Distribute)

−x+6=4

Step 2_ −x+6−6=4−6

−x=−2

Step 3_ −x equals -2

−1 -1

x=2

**Answer:**

zero goats and 120 Ilamas to get profit of $15,120

**Step-by-step explanation:**

Goats: G

Ilamas: l

Explicit constraints:

2G + 5l ≤ 400

100G+ 80l≤ 13,200

Implicit constraints

G≥0

I≥0

P= 84G+ 126l

See attachment for optimal area

substituting coordinats of optimal region in profit equation to get profit

When G= 132, l=0

P=84(132) + 126(0)

P=11,088

When G=0, l=120

P=84(0)+ 126(120)

P = 15120

When G= 100, l=40

P=84(100)+126(40)

P=13440
