Here's what I have so far - x – 3 = 2x – 13 simplify = x – 3 + 3 = 2x – 13 + 3 now we have = x = 2x - 10 Now I'm stuck!

I still don't understand.

what you have above is correct to continue put the variable on one side the number on the other

How do I remove 2x from the equation?

divide each side by -1 x = 10
Shiree19
  • Shiree19
so I do x - 2x = 2x - 10 - 2x which equals x - 2x = 10 then I divide by -1 (where did you get the -1 from?)

Shiree19
  • Shiree19
so it's x * -2x? I multiply each side by -2x? How do you make 2x negative?
triciaal

1x -2x = -1 x no number before the variable is understood as 1
Shiree19
  • Shiree19
okay. so x =1 which equals 1x.

I have no idea what that means....
triciaal
  • triciaal
x -2x subtract 1x - 2x = -1x
triciaal
  • triciaal
read it again slower it shows examples that 1 is understood
Shiree19
  • Shiree19
okay just a min
Shiree19
  • Shiree19
Oh I get it! x - 2x = 1x - 2x = -1x = -x -x = -10 and two negatives = a positive so x = 10
triciaal
  • triciaal
yes

Thanks so much!
