Answer:
Step-by-step explanation:
Note that if you combine the two equations in this SYSTEM, you get the (true) equation 0 = 0. Thus, there are infinitely many solutions.

Step-by-step explanation:
5(-7)-2(-7+3)^2
=-35 - 2(-4)^2
=-35 - 2x16
=-35 - 32
=-67
Am i right? :o
Good evening ,
Answer:
<h2>8 chickens</h2><h2>8 horses</h2>
Step-by-step explanation:
let c = the number of chickens
let h = the number of horses
You have to solve this system
h + c = 16
4h + 2c = 48
h + c = 16 ⇒ h = 16 - c
If we substitute h=16-c in the second equation we will get :
4(16-c)+ 2c = 48
Then 64 - 4c + 2c = 48
Then 2c = 64 - 48 = 16
Then c = 8
Since h = 16 - c then h = 16 - 8 = 8
