Answer:
x=12 y=9
Step-by-step explanation:
first we need to do this equation to get X
we don't have y so y=0
x-(0)=12
we eliminate the 0
x=12
now, we have X, now we need to find Y
substitution
x+y=3
12+y=3
y=3-12
y= 9

The answer is one over fourteen because there are 8 white eggs (remember the 10 brown eggs), and half of them (the white ones) are cracked, so four. And, if you randomly grab an egg, there is 1/14 of a chance you could grab a cracked, white, egg.
For this case we have the following system of equations:
To solve, we clear "x" from the second equation:
We substitute "x" in the first equation:
We clear the value of the variable "y":
We look for the value of the variable "x":
Thus, the solution of the system is given by:
