Answer:
x = 8 is the answer
Step-by-step explanation:
In order to find the solution of Equations using Cramer's rule
we shall find matrices
D= [tex]\left[\begin{array}{ccc}5&-3\\1&-2\end{array}\right][/tex]=
[tex]D_{1} = \left[\begin{array}{ccc}4&-3\\-16&-2\end{array}\right][/tex]
l D l = Determinant formed by coefficient of variables
Here l D l = 5X(-2) - 1X(-3)= -10+3 = -7
l D1 l = Determinant formed by replacing first column In D by numbers on the right side of the equations
Here l D1 l = 4X(-2)- (-16)X(-3)= -8-48 = -56
here x is given by [tex]\frac{l D1 l}{l D l}[/tex]
x = [tex]\frac{-56}{-7}[/tex]
x = 8
