Answer:
If a<b, x<2
If a>b, x>2
Step-by-step explanation:
ax-bx>2a-2b, (a-b)x>2(a-b)
If a>b, x>2(a-b)/(a-b)=2
If a<b, x<2(a-b)/(a-b)=2
<span>Cows (C)→ 4 legs
Chickens (c) → 2 legs
C+c=13 |×4
4C+2c=36
4C+4c=52
4C+2c=36
--------------- (-)
2c=16
c=8 chickens
C=13-8
C=5 cows

Answer:
multiply (x-1) to both sides and then subtract three from both sides
3 = (x-1)(x+1)
3 = (x^2 -1)
0 = x^2 - 4
(x-2)(x+2) = 0
x = 2
x = -2
