Question

On Saturday, Lukas drove 4x – 5 miles. On Sunday, he drove 3x – 10 miles. What is the difference in miles driven?

Answer 1

Distance drove by Lukas on Saturday = (4x - 5) miles

Distance drove by Lukas on Sunday = (3x - 10) miles

To find the difference in miles driven by Lukas = Distance drove by Lukas on Sunday - Distance drove by Lukas on Saturday

Difference in miles driven by Lukas = (3x - 10) - ( 4x - 5)

= 3x -10 - 4x +5

= -x - 5

Difference in miles driven by Lukas = ( - x - 5) miles

Answer 2

4x-5-(3x-10)=4x-5-3x+10=x+5 miles is the difference
