Item 6 for what value of a is 8x−8+3ax=5ax−2a an identity?
Readme [11.4K]

Let's rewrite the expression as

8x+3ax-5ax = 8-2a \iff 8x - 2ax = 8-2a \iff 2x(4-a) = 2(4-a)

So, if a \neq 4, you may divide both sides by 4-a, the equation becomes 2x=2, and the only solution is x=1, which means that this is not an identity (an indentity is tautologically true, no matter the value of x).

If instead a = 4, you are multiplying both sides by zero, so the equation becomes

2x \cdot 0 = 2 \cdot 0 \iff 0=0

So, it doesn't matter which value for x you choose, because you will always end up with 0=0, which is obviously always true.
