A shopper paid $2.52 for 4.5 pounds of potatoes and $7.75 for 2.5 pounds of broccoli. What is the unit price of each item she bought?

Solution:

Given that,

Unit price is the price of 1 unit

A shopper paid $2.52 for 4.5 pounds of potatoes

Thus unit price is $ 0.56 per pound of potatoes

$7.75 for 2.5 pounds of broccoli

Thus unit price is $ 3.1 per pound of broccoli

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
