-2x-x=5
-3x=5
x=-5/3
if you couldn't figure it out i might be because you overlooked these things: minus is the same as adding a negative and you can always put a 1 in front of x and you can combine the x's

well -2x - x = -3x
therefore -3x = 5
you can reverse the signs of the equation to get
3x = -5
x = -5/3
x = -1.6
Thats what i reckon the answer is
hope this helps

-2x - x = 5
-3x = 5
x = -5/3
What's the issue? That's about as easy as they come. Did you write the problem correctly?

-2x-x=5
-2x and x are similar, so subtract
-3x=5
divide both sides of the equation by -3
x=(-5/3)
