Question

simplify :

1. 3x + 7h + y - (-8k) - 11x +65 y + (-40k)

confused???????

and i had brainstormed myself and the answer is not in the book???

Answer 1

1. 3x + 7h + y - (-8k) - 11x +65 y + (-40k)

                      

         -   first you will perform the operation needed in the sentence  

                      

                    # combine like terms ,thus:



          first_       3x - 11x = -8x

     second_       7h will be remain on its own value

         third_       +y + 65y =66y

         forth_       -(-8k) + (-40k) = -32k

so the final answer would be

              -9x + 7h + 66y -32k

                        thats it hope I made a help to you ...gudluck:)

Answer 2

Here, you just have to collect similar terms. Similar terms have the same literal part; in this expression, the literal parts are x, h, y and k.

Thus,

3x + 7h + y - (-8k) - 11x +65 y + (-40k)

= 3x - 11x + 7h + y + 65y - (-8k) + (-40k)

= -8x + 7h + 66y + 8k - 40k

= -8x + 7h + 66y - 32k Answer

Answer 3

-8x+66y-32k+7h = 0

Answer 4

3x + 7h + y - (-8k) - 11x +65 y + (-40k)

3x - 11x + y + 65 y + 7h - (-8k) + (-40k)

- 8x + 66y + 7h - 32k
