I believe Lance meant to write x = -5/18

I am wondering why you have two minus signs before the number 13. Two minuses make a plus, but usually they are not written that way.

combine like terms
-18x=5
solve for x
x=5/18

what does x equal in... -2x-18=16x--13

To find the value of x in the equation -2x - 18 = 16x - (-13), we need to simplify the equation and solve for x. Let's break it down step by step:

1. Simplify the equation by removing the double negative sign before -13. Double negatives become positive, so -(-13) is the same as +13.
-2x - 18 = 16x + 13

2. Combine like terms by moving all the x terms to one side of the equation and the constant terms to the other side. To do this, we'll subtract 16x from both sides and add 18 to both sides.
-2x - 16x = 13 + 18

Simplified equation: -18x = 31

3. Solve for x by isolating x on one side of the equation. To do this, divide both sides of the equation by -18.
-18x / -18 = 31 / -18

x = -31/18

Therefore, based on the given equation, x is equal to -31/18.
