Answer:

A = -12

Step-by-step explanation:

A   put in -2 for 'x' in the equation to find value

       2(-2)  - y = 8       add 4 to both sides

              -y = 12

               y = -12              

        I think YOU can now find B and C  with this method !
A= -12
B= -8
C= -4


2x-y = 8 so reformatting by getting the y to be alone on the right side,
then 2x-8 = y
Just plug the value if x in and you find y

Have a nice day!
