Okay I am not 100% sure because that is an extremely confusing question. But here is what I got.
(A) 2c² = 2bc + ac/2 Given
(B) 4c² = 2bc + ac Multiplication and Distribution
(C) 4c = 4b + a Division and Distribution
(D) 4c - a + 4b Subtraction
(E) 4b = 4c - a Symmetric
Distribute the negative:
6x-3-8x-11
Combine like terms:
-2x-14
Simplify by factoring:
-2(x+7)
Answer:
