You want to get rid of the -2x on the right side, so
just do something to both sides that cancels out the -2x
on the right side. That happens to be adding 2x to both sides
You can think of it as subtracting a -2x from both sides, so
I'll do it that way

now subtract 2 from both sides

and this equals

so x can be +3 or -2 answer
check answer

OK
