Answer: X=6

Step-by-step explanation: you can set AB plus BC to AC because they both are equal to the full line so..

2X-2+3=3X-5

First off add like terms so..

-2+3= 1 and then add 5 to the negative 5 and 1 which now leaves you with

2X+6=3X

Now you see more like terms ( 2X,3X)

Now subtract 2X from 3x which will leave you with

6=1X

Now to separate X and get you answer you see it’s 1X and 1X = X prior to defined answer, therefore you will be with X=6. Have a great day

we can made a visula representation of the problem so:

So we can made an equation like:


\begin{gathered} AB+BC=AC \\ 2x-2+3=3x-5 \end{gathered}

and we can solve for x so:


\begin{gathered} 2x+1=3x-5 \\ 5+1=3x-2x \\ 6=x \end{gathered}

AB = 2x-2, BC = 3 and AC = 3x-5 find x-example-1
