8-20x=6-3+9x
-29x=-5
29x=5  I would go with C

How does 6-3+9x = -5?

anonymous · Answer

I also don't understand how 8-20x = -29x. If you could draw out how you solved the equation or expanded a little on the steps part I'd really appreciate it.

A better question is how does 6-3-8 = -5
You are subtracting 8 from both sides, noticed it is no longer on the left.

anonymous · Answer

Ah, I see..

radar · Answer

Using algebra you may add or subtract from one side as long as you treat both sides the same way, I also subtracted 9x from both sides.

The next time I will show it more clearly.  Do you follow with understanding?

anonymous · Answer

Yes, I know how you got the answer now.
Thank you very much :)
