WILL BE MARKED AS BRAINLIEST!!

(52 + 4 − 6)− (−52 − 3 + 15)

(52 + 4 - 6) - (-52 - 3 + 15) = 90

Step-by-step explanation:

To solve:

(52 + 4 - 6) - (-52 - 3 + 15)

Let's attack the question step after step and be mindful of our signs

BODMAS will be our giude. It means we will solve :

BRACKETS first

OF

DIVISION

MULTIPLICATION

ADDITION

SUBTRACTION.

Anyway, addition and subtraction can he overlapped.

Let's go now!

(52 + 4 - 6) - (-52 - 3 + 15)

=(56 - 6 ) - ( -55 + 15)

=(50) - ( -40)

We will have to open the brackets at this point and be very careful of the signs

= 50 - * - 40

= 50 + 40

= 90

Let's keep learning!

Maths is fun

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.
