Answer:
-2
Step-by-step explanation:
16= -4(x-1)+4
16 - 4 = -4x + 4
12 = -4x + 4
12 - 4 = -4x
8 = -4x
x = 8 ÷ -4
x = -2
Answer:

Step-by-step explanation:
It is about as easy to try the solutions as it is to find them from scratch.
__
However, we can determine which one it is by adding twice the second equation to the first.
(-2a +3b) +2(a -4b) = (14) +2(3)
-5b = 20
b = -4 . . . . . . matches the first choice
Answer:
Step-by-step explanation:
So, it's x*x+x*-3+-4*x+3*-3
That simplifies to x^2 - 7x + 12
