Solve 2(x+6)=2(6+13x).

2x=26x

It is not correct mathematically!

Step-by-step explanation:

Simplify the braces

2x+12=12+26x

You have 12 on both sides so you can simply remove it.

The result: 2x=26x

1/6 = x

Step-by-step explanation:

To solve 2(x+6)=2(6+13x) you have to distribute the coefficients first by turning 2(x+6)=2(6+13x) into 2x+16=12+26x.

Then, you have to subtract 2x from both sides to get 16=12+24x and subtract 12 from both sides to get 4=24x.

Lastly, divide both sides by 24 to get 4/24 = x and simplify it to 1/6 = x

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
