This is a square matrix whose entries are real and rows and columns are orthogonal unit vectors.
y=9
Step-by-step explanation:
y=2(6)-3
y=12-3
y=9
First solve for the trig function 'cot'

Next take the sqrt of both sides (include plus/minus)

Now take reciprocal of both sides, this will change trig function to 'tan'
(cot = 1/tan)

Finally use the unit circle or inverse tan on your calculator to find x.
There will be 4 solutions, one for each quadrant.
