What is the answer to -4x-10x

you have to add similar elements

-4x-10x=-14x

Mark me brainliest if it helped

-14x is your answer

Step-by-step explanation:

when subtracting a negative with a positive you add and include the negative sign. this is because instead of decreasing, you are increasing your negative. another example is:

-2 - 6 = -8

on a number line, you would be going backwards. Your median is 0 everything to the left of zero is negative and goes up, everything to the right of zero is positive and goes up.

example:

-8, -7, -6, -5, -4, -3, -2, -1, 0 1, 2, 3, 4, 5, 6, 7, 8

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.
