An equation is shown below:

5(2x - 8) + 15 = -15

Write the steps you will use to solve the equation and explain each step.

x=1

Step-by-step explanation:

To solve, we need to get x by itself. To do this, preform the opposite of what is being done to the equation, and everything that is done to one side, must be done to the other.

5(2x-8)+15= -15

First, subtract 15 from both sides, since 15 is being added

5(2x-8)+15-15=-15-15

5(2x-8)=-30

Next, divide both sides by 5 since 5 is being multiplied

5(2x-8)/5= -30/5

2x-8= -6

Add 8 to both sides, since 8 is being subtracted

2x-8+8= -6+8

2x= 2

Divide both sides by 2, since 2 is being multiplied

2x/2= 2/2

x=1

(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
