Question

Please someone do this for me

Answer 1

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!

Answer 2

A = -12

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 !
