The Eastons traveled 160 miles on a trip to Grandma’s house. At the end of the trip the odometer read 7,456 miles. Write and solve an equation to find the odometer reading x at the beginning of the trip.

x+160=7456

x=7456-160

x=7296 miles on the odometer

Step-by-step explanation:

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.
