Step-by-step explanation:
2(heads) + 2(goats) = 140
Heads are given, so we get:
2(52) + 2(goats) = 140
104 + 2(goats) = 140
2(goats) = 36
goats = 18
Since we know the number of goats, we know the number of chickens.
34Chickens and 18 goats.

see answer above for your question
Answer:
y = -6/7
x = 6/49
Step-by-step explanation:
-7x -y = 0
7x +8y = -6
Add the two equations together to eliminate x
-7x -y = 0
7x +8y = -6
-----------------------
7y = -6
Divide by 7
7y/7 = -6/7
y = -6/7
Now we need to find x
-7x -y = 0
-7x -(-6/7) =0
-7x +(6/7) =0
-7x +6/7 -6/7 =0-6/7
-7x = -6/7
Divide each side by -7
-7x/-7 = -6/7 *-1/7
x = 6/49
