Hm... now it seems you missed the plus sign...

You need to solve for x?

Use the distributive law first.

$3(x+1) = -2(x - 1) -4$

$3x + 3 = -2x + 2 - 4$

Simplify now and send all the terms in x on one side and all the other terms on another side of the equal sign.

Can you get it now? Post what you get! :)

hmm yeah I did misplaced a plus sign
I then subtract 2 from oppisites sides of the equation which leaves me with
3x + 1 = -2x - 4
-1 -1
3x = -2x -5
-2x -2x
x = -5

Am I right..?

Not quite.

$3x = -2x -5$

Add 2x, not subtract.

Because -2x -2x = -4x.

So, in your work, you are doing:

3x - 2x = -2x -5 - 2x

x = -4x -5
