I believe you drop the | lines. Then I think that it turns into 2x + 1 = 10. Next I believe you subtract 1 from each side to get 2x = 9. Then you divide both sides of the equation by 2 to get x = 4.5. To check your work simply plug in 4.5 for x. 2 times 4.5 is 9, 9 + 1 = 10. I hope this helped. P.S. I have learned how to do most of those problems accurately
