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

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
