Hello Again!
What you want to do first is add 4 to -4 and to -13. After doing so, you'll equation will look a little something like this...
-3x=9
You'll then want to divide both -3 and 9 by -3. After doing so, the equation will look like this...
x=-3
Your answer is x=-3
I hope this helps

y = 300-300
y = 0
wheb y =0 that means that the height is 0
