Answer: 
Step-by-step explanation:
1. Substitute
into first equation and solve for "x" in order to find the x-intercept of the first line:

2. Substitute
into the first equation and solve for "y" in order to find the y-intercept of the first line:

Knowing that first line passes through the points
and
, you can graph it.
3. Substitute
into second equation and solve for "x" in order to find the x-intercept:

4. Substitute
into the second equation and solve for "y" in order to find the y-intercept of the second line:

Knowing that second line passes through the points
and
, you can graph it.
The solution of the system of equations is the point of intersection between the lines. Therefore, the solution of this system is:

5/12(poetry) + 2/5(biographies) = 25/60 + 24/60 = 49/60
60/60 - 49/60= 11/60
11/60 are the remainder of the books in the shipment.
So I believe that the position the triangle is sitting in is the original position that the question started with correct? (Wasn't sure if you moved it before the screenshot or not)
So for all three points of the triangle, move each of them 6 units to the left since the rule has (x-6). If it was x+6, it should be 6 units to the right then.
After you move it 6 units to the left, move the points (all three) 4 units down since (y-4) means moving in the y-direction downward!
That should be the new place for the triangle to be positioned.
Hope this helps!
