Answer:
It's simple
Step-by-step explanation:
See what I did there? Simple?
So, since we have a cubic equation with 4 terms, the first thing we should try is factoring by grouping, so:
Now that we've factored our equation, we can use ZPP and break it up:
So, our solutions are:
Austin should pay $75 the first month, and 37.50 for the remaining of the 2 months
For this case we have:
By properties of the radicals 
So:
.
Now, for power properties we have:
Thus, 
So:
in its radical form
Answer:
in its simplest form.
in its radical form
1. Multiply each equation so they end up with the same coefficient
2. Subtract your second equation from the first
3. Solve for one of the variables (I tend to solve an equation that only contains 2 variables if possible. So it would be if you have one question with x and y, solve for the easier one)
4. Substitute the variable you found in the least step into one of the other equations and find a second variable.
5. Substitute both variables you found into the last equation and there you should be left with x, y, and z :))
I hope this helped sksjsk if it didn’t I could write it out to hopefully help more :)
