Answer:
x = -3, y = 1
Step-by-step explanation:
To find the value of x and y, find the determinant of original matrix, which would be 21.
Then, substitute the value of x with the solutions to the equations and find the determinant of that matrix, which is -63.
Cramer's rule says that Dx ÷ D is the value of x. So, -63 ÷ 21 = -3.
So, the x-value is -3.
You can find the determinant of the y-value in the same way, and you'll find out that y = 1.
Hope this helped! :)

Answer:
let's see what to do buddy...
Step-by-step explanation:
To find the output of a number in a function, we must put it in the equation of the function instead of the <em><u>x</u></em> .
So to find output of ( x = 4 ) , we must put 4 instead of <em><u>x</u></em> in the equation .
Let's do it :

So the output number of ( x = 4 ) is <em><u>2</u></em><em><u>3</u></em> .
