Answer:
x=3
Step-by-step explanation:
Step 1: you have to replace y with x-6 to make it all one equation (as seen in the picture below)
Step 2: write it all together so: x-6= -2x+3
Step 3: add 2x on both sides to cancel out the negative so: x+ 2x and -2x+2x
Step 4: add 6 on both sides to cancel out the negative so: -6+ 6 and 3+6
Step 5: divide 3 by 3x and 9 to get x

The unit cost
Pick any point on the dots of the graph; we have:
The unit cost is then calculated as:
Now, as the pizza is circular, so it does not matter about the box shape. If the box shape increases or decreases, the pizza shape is the same.
Now, we have been asked about the largest pizza radii that can fit in the box, so we will consider the shortest value of the box.
The width is given as 14 inches. There is a 2 inch border around the pizza. So, the width is 14-4 = 10 inches. (Now assume this as the diameter of pizza)
And the radius is = inches.
So, the largest pizza that can fit in the box will have a radius of 5 inches.
