Can you me what i did wrong and me solve this equation

Remark

The order is not quite correct.

-  7 + (-11 * 5 - - 7) ÷ - 6

The - - 7 becomes a plus

- 7  + (- 55 + 7) ÷ -6      

This is where the real problem is. -55 + 7 goes down. This gives - 48

- 7 + [( - 48) ÷ - 6]

You do  the division by - 6 before adding. Adding - 7 to the result of the division is your very last step. Think BedMas.

-7 + (8)

The 8 is the result of the division. -48/-6 = 8. the -7 and the 8 are added. You get 1.

The --7 in parentheses means +7. The symbol "÷" means "divided by". Division is done before addition or subtraction.

Whenever an even number of minus signs is involved in multiplication or division, the result is a positive number. An odd number of minus signs results in a negative number.

i think because what else can be a sample of every member

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.
