Using Cramer’s rule, what is the value of x in the solution to the system of linear equations below? -1/2X + 3Y = -4
-X -Y = -1

A)-2
B)-1
C)1/2
D)2

Cramer's rule tells you that the value of x in the system of equations,

- 1/2x + 3y = - 4.

- x - y = - 1.

is given by,

x = ce - fb/ae - bd

x = (- 4 × - 1) - ( - 1 × 3)/(- 1/2 × - 1) - (3 × - 1)

x = 4 - (- 3)/1/2 - (- 3)

x = 4 + 3/1/2 + 3

x = 7/1 + 6/2

x = 7/7/2

x = 7 × 2/7

x = 2.

Correct choice => [D] - 2.
