Question

The Eastons traveled 180 miles on a trip to Grandma's house. At the end of the trip the odometer read 8,246 miles. Write and solve an equation to find the odometer reading x at the beginning of the trip.

Answer 1

8246=x+180

x=8066 miles

Explanation:

Let the initial readings be x

The final reading is the sum of initial reading and distance covered hence

Final=Initial + distance covered

Substituting 8246 miles for the final miles and 180 miles for the distance traveled to Grandma's house

8246=x+180

Solving for x

x=8246-180=8066 miles
