Ok so to solve its X+9=2X-8
Then you minus the x that’s alone to cancel it out but you do it on the other side too so now it’s
X+9=2X-8
-X -X
9=X-8
So now you add 8 to both sides to cancel out the negative 8. So now it is
9=X-8
+8 +8
Now you have
17=X so (X=17)
You’re welcome and have a great day and night!!!!!!
