Answer:


Step-by-step explanation:
Arrange the equations so that all the variables are in columns (x as the first column, y as the second, equals a number as the third):
-11x - 4y = 36
5x + 5y = -10
Define and edit Matrix A. We need a 3 x 2 matrix. Input the coefficients and constant:
![\left[\begin{array}{ccc}-11&-4&36\\5&5&-10\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-11%26-4%2636%5C%5C5%265%26-10%5Cend%7Barray%7D%5Cright%5D)
Find rref function, enter matrix A: rref([A]) (press enter)
This gives you:
![\left[\begin{array}{ccc}1&0&-\frac{44}{7}\\0&1&\frac{58}{7}\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%26-%5Cfrac%7B44%7D%7B7%7D%5C%5C0%261%26%5Cfrac%7B58%7D%7B7%7D%5Cend%7Barray%7D%5Cright%5D)
which means:


8 223/285 I think that is the right answer if no i am sorry
Answer:
9
Step-by-step explanation:
The absolute value of any number is just its distance from 0.
-4 is 4 away from 0, so its absolute value is 4.
-5 is 5 away from 0, so its absolute value is 5.
Therefore, the equation is basically just asking what is 4 + 5, which is 9 :D.
Answer:
: 1: Exact form : v = - 1/27
: 2 : Decimal form : v = -0.037037037037037037037037...
Step-by-step explanation: Multiply the equation to remove your variable (v) from the denominator.
I hope this helps you out.
