Answer:6:15
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
Answer: x=5 y=-6
(5,-6)
Step-by-step explanation:
Solve by elimination

multiply x-5y=35 by 3
= 3x-15y=105


-

divide 9 on both sides
y= -6
Now solve for x
you must plug in -6 for y in either equations
i plugged in -6 for y in 3x-15y=105




subtract 90 on both sides

The given matrix is A = ![\left[\begin{array}{cc}2&2&1&3\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D2%262%261%263%5C%5C%5Cend%7Barray%7D%5Cright%5D)
The inverse of a matrix is given by
...(1)
Now, determinant of matrix A is
|A| = 
= (3)(2) - (2)(1)
= 6 - 2
= 4
Now, adjoint A will be
