2x-10=2. (Answer=6)
2x=12 (you move the -10 to the other side of the equation to make it positive)
Then you divide by 2
2x divided by 2 equals x 12 divided by 2 is 6
So your number is 6. x=6
And you can check this by redoing the equation but putting 6 instead of x
2(6)-10=2
12-10=2
2=2
This equation is true therefore, your unknown number is 6
