  1. Yes. Look at this example Here,
  2. I can write. Solve.
  3. So
  4. for
  5. X
  6. here two X plus one equals three. Okay. How can we solve this equation
  7. and to solve the equation? You know, we should understand that what the equation is
  8. we have one unknown here. X is unknown. So X represents here One number.
  9. We multiplied
  10. X by two and then we add it. One, we've got three. So what is what number is dead?
  11. Yeah.
  12. I can also express this.
  13. Multiply a number by two and 81. You've got three. What is that number?
  14. So
  15. the easy thing is we can substitute here any symbol
  16. and generally we are using X.
  17. So I will
  18. start
  19. from the last operation.
  20. Since we multiply X by two. And that s one. The last operation is edition.
  21. So I'll subject one from each side
  22. to remove
  23. to get rid of one from here or to remove the one here.
  24. So one minus one is zero. It remains two x and three minus one is two
  25. and then next means we should multi. Do
  26. we multiply X by two?
  27. So in under an inverse operations division should try to exploit to
  28. and then two by two.
  29. So we got X equals one.
  30. This is the solution.
  31. I hope it's helpful.
  32. Thank you for listening.
  33. Yes.
