3x-4(2+3x)=82 I have to get an answer of x=-10 but I cant seem to get it. Can someone answer it and give me an explanation please?

x=-10

Step-by-step explanation:

3x-4(2+3x)=82

3x-(4*2)+(4*3x)=82

3x-8-12x=82

-9x-8=82

-9x-8+8=82+8

-9x=90

-9x/-9=x

90/-9=-10

x=-10

10 isn't the right answer

Step-by-step explanation:

multiply everything in the parenthesis by -4

you would get 3x-8-12x=82

then combine like terms to get -9x

once your equation is in simplist form it will look like

-9x-8=82

next you add 8 to the 82

-9x=90

then divide 90 by -9 and you would get

x=-10

(x3 + 6x2 + 2x - 6) • (x - 1)

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
