Could you please type out the question, it seems a bit unclear

OpenStudy (ltrout):

The easiest way to solve this is to replace b with each value in your answer choices until it lines up with -17x-8.

OpenStudy (the_puppet1):

Marina simplified the expression 4x + 5(-4x - b) - (x - 2 to be -17x - 8. What was the value of b? A) -6 B) -2 C) 2 D) 10

Itrout has this one :)

OpenStudy (ltrout):

So I'll help you on one. I'll replace the B's with the answer choice found in A. So 4x+(-6)(-4x-(-6))-(x-2). I'll rewrite that to make it easier. 4x-6(-4x+6)-(x-2). 4x+24x-36-x-2. 4x+24x-x-38. 28x-x-38. 27x-38. So we know A isn't an answer. Would you like to try it with B?

OpenStudy (the_puppet1):

Sure?

OpenStudy (ltrout):

So just replace the B in the equation with (-2) and make sure to use parenthesis to make it easier to see/read. :)
