Answer:
90 goats
Step-by-step explanation:
Number of chickens in farm = (1/5) of 150
= 
= 1 * 30
= 30
Number of cows in farm =
= 1 * 30
= 30
Number of goats in farm = 150 - (30 + 30)
= 150 - 60
= 90
5x=-10-5y
Add 5y for both side
5x+5y=-10
-
5x+10y=-25
=
-5y=15
Divided -5 for both side
y=-3
5x+10y=-25
5x+10(-3)=-25
5x-30=-25
Add 30 for both side
5x=5
Divided 5 for both side
x=1. Hope it help!
