As you move to the right of this place value chart you are multiplying by what value

 1/10 or 0.1

For example, going from 700 to 70 is

700*(1/10) = 700*0.1 = 70

which is us going from the hundreds place value to the tens place value.

If we move to the left instead of right, we would multiply each item by 10.

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.
