Answer:
Step-by-step explanation:
30 = -5(6n + 6)...distribute the 5 thru the parenthesis
30 = -30n - 30....add 30 to both sides
30 + 30 = -30n
60 = -30n....divide both sides by -30
-60/30 = n
-2 = n <===

Answer:


Step-by-step explanation:
Solve the following equation:
![\left[\begin{array}{ccc}3&2\\5&5\\\end{array}\right] \left[\begin{array}{ccc}x_{1}\\x_{2}\\\end{array}\right] + \left[\begin{array}{ccc}1\\2\\\end{array}\right] = \left[\begin{array}{ccc}2\\-3\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%262%5C%5C5%265%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx_%7B1%7D%5C%5Cx_%7B2%7D%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%2B%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%5C%5C2%5C%5C%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%5C%5C-3%5C%5C%5Cend%7Barray%7D%5Cright%5D) 
 
-In order to solve a pair of equations by using substitution, you first need to solve one of the equations for one of variables and then you would substitute the result for that variable in the other equation:
-First equation:
 
-Second equation:
 
-Choose one of the two following equations, which I choose the first one, then you solve for  by isolating
 by isolating 

-Subtract  to both sides:
 to both sides:
 
 

-Subtract  to both sides:
 to both sides:


-Divide both sides by  :

-After you have the value of  , substitute for
, substitute for  onto this equation, which is
 onto this equation, which is  :
:


-Multiply  and
 and  :
:


-Since both  and
 and  have the same denominator, then add the numerators together. Also, after you have added both numerators together, reduce the fraction to the lowest term:
