You and your friend race from point A to point C. You run from A to B and then from B to C. Your friend runs from A to D and then from D to C. You run at an average rate of 7.8 miles per hour and your friend runs at an average rate of 8.1 miles per hour. Is it possible to determine who wins the race?

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
