The value of x in the equation.
19= 1+ x

ok this means that adding 1 to x equals 19

so if we subtract one from 19

19-1=18

so x=18

Hope This Helps!!!

x=18

Step-by-step explanation:

To solve for x, remember to ask yourself what is being done to x, then do the opposite to cancel it out and get x by itself. In this case, what is being done to x? 1 is added to it. So you have to do the opposite, which is subtract 1. You have to subtract 1 from each side because what you do to one side, you always have to do to the other.

19=1+x

19-1=1+x-1

18=x which is the same as x=18

(x3 + 6x2 + 2x - 6) • (x - 1)

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
