Add and subtract fractions with negative signs. -4/5 + 6/5=?

2/5

Step-by-step explanation:

when adding a positive to a negative, you can reverse the order so that you can remove the addition sign:

so instead of -4/5 + 6/5

you can make it 6/5 - 4/5 which equals 2/5 or .4

0.4 or 2/5

Step-by-step explanation:

The fractions already have the same denominator so all that is left to do is add the numerators

-4+6=2

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.
