What is the solution to the following system of equations?
{y-2y=4
{y=5x+1

(-1,-4) or x = -1, y = -4

Step-by-step explanation:

You can solve this system of equations by (in the first equation) by isolating the variable so that y = -4. Now that you know this, you can enter this info into the second equation to isolate the x value, which would be -1. You can see if this is correct by plugging the numbers back into the equation.

to determine the unit cost your would divide the total cost by the number sold.
