Solve the System of Equations

Problem: You have a small ranch with chickens and goats. There are 80 heads and 216 legs. Find the number of both chickens and goats.
Write 2 equations
Solve the System ( use the substitution method )
Graph both equations (use Desmos or graph by hand)

you should at least use a calculater

step-by-step explanation:

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

20

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
