Using Cramer's Rule, what is the value of x in the solution to the system of equations below?

-X-3y = -3
-2x-5y=-8

X=9 AND Y= -2

Step-by-step explanation:

Step: Solve−x−3y=−3for x:

−x−3y=−3

−x−3y+3y=−3+3y(Add 3y to both sides)

−x=3y−3

−x

−1

=

3y−3

−1

(Divide both sides by -1)

x=−3y+3

Step: Substitute−3y+3forxin−2x−5y=−8:

−2x−5y=−8

−2(−3y+3)−5y=−8

y−6=−8(Simplify both sides of the equation)

y−6+6=−8+6(Add 6 to both sides)

y=−2

Step: Substitute−2foryinx=−3y+3:

x=−3y+3

x=(−3)(−2)+3

x=9(Simplify both sides of the equation)

B)

|-3 -3|

|-8 -5|

——— =9

-1
