from the second:

A=[3 -1]. -2B

[-5 0]

input this into 1

2([3 -1]) -(2B) -B =[1 3]

([-5 0]). [0 5]

[6 -2] -4B-B=[1 3]

[-10 0]. [0 5]

-5B=[1 3] -[3 -1]

[0 5]. [-5 0]

-5B= [1-3 3+1]

[0+5 5+0]

B= [-2/5 4/5]

[1 1]

A=[(19/5) (3/5)]

What is 5/14+1/6 I really need help
-Dominant- [34]
First thing to do, when you have to add 2 fractions, you have to make both denominators equal. 14/6 = 0.84, so can't multiply or divide any fraction by a whole number to get the other denominator.
So, you multiply each fraction by the denominator of the other fraction. Which means that you multiply 5/14 by the denominator of 1/6 which is 6, and you multiply 1/6 by the denominator of 5/14 which is 14.
5/14 + 1/6 = 30/84 + 14/84
Then you join both fractions to make them under one denominator, since both denominators are equal.
30/84 + 14/84 = (30+14)/84 = 44/84.
Now, you need to simplify the fraction: you divide both numerator and denominator by 4:
44/84 = 11/21

So 5/14 + 1/6 = 11/21

Hope this Helps! :)
