PLEASE HELP Explain what is happening at this step in the solving equation process.
10 − 6 x = 4 + 5 x

7-6x=1+5x

3 ( 4 x − 3 ) = − 15

4x-3=5

5x/-3=12/1

5x=-36

−3 ( 4 x − 3 ) = − 15

4x-3=5

Step-by-step explanation:

It looks like you have four different equations here.

As a rule, each step in the solution involves one of the properties of equality: addition, subtraction, multiplication, or division. These properties let you do the same thing (one of these operations) to both sides of the equation.

__

1. 10 − 6 x = 4 + 5x

  7 -6x = 1 +5x . . . . 3 was subtracted from both sides*

__

2. 3 ( 4 x − 3 ) = − 15

  4x -3 = -5 . . . . . both sides were divided by 3

__

3. 5x/-3=12/1

  5x=-36 . . . . both sides were multiplied by -3

__

4. −3 ( 4 x − 3 ) = − 15

  4x -3 = 5 . . . . both sides were divided by -3

* For this equation it would have been more useful to subtract 4 to get ...

  6 -6x = 5x

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
