Respuesta :
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
The difference in distance driven by lukas is; (x + 5) miles
Distance lukas drove on saturday; 4x - 5 miles
Distance lukas drove on sunday; 3x - 10 miles
Thus, to get the difference in miles of distance he drove, we will subtract the distance he drove on Sunday from the distance he drove on Saturday to give;
Difference in distance driven; 4x - 5 - (3x - 10)
⇒ 4x - 5 - 3x + 10
⇒ (x + 5) miles
