(-9b^9-11n) - (6b^9-7n) in its simplest terms

Mathematics

Hello, there!


In this case, we can get rid of the parenthesis 

-9b^9 - 11n - 6b^9 + 7n

Now, we will simplify like terms.

-9b^9 and -6b^9 are like terms.

-9b^9 + -6b^9 = -15b^9

-11n and 7n are like terms (it is 7n because when you subtract, you switch signs.)

-11n + 7n = -4n

So, our final answer is -15b^9 - 4n


I hope I helped!

wolverine [178]

Answer:

X=4 Hope it helps Lol

Step-by-step explanation:

  5*x-3-(21-x)=0

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  6x - 24  =   6 • (x - 4)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    6   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x-4 = 0

Add  4  to both sides of the equation :

                     x = 4

One solution was found :

                  x = 4
