How do i solve for n in this problem -6n - (3n - 9) + 5n = -4 (2n - 8)​

-6n -(3n - 9) + 5n = -4 (2n - 8)

-6n -3n +9 +5n = -8n +32

-9n +5n +9 = -8n +32

-4n + 9 = -8n +32

8n - 4n = 32 - 9

4n = 23

n = 23/4 = 5.75

add the table and i will answer correctly

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
