Question

Solve for x. 3x - 1 = 27

Answer 1

The equation given in the question is
3x - 1 = 27
3x = 27 + 1
3x = 28
x = 28/3
  = 9 1/3
  = 9.33
So the value of x is 9 1/3 or 9.33. i hope there is nothing complicated in the procedure and so it is easy for you to understand. You can always use this method for solving similar problems in future without requiring any additional help from outside. Only be careful about the calculation part. Other than that there is nothing tough about the given problem.

Answer 2

3x -1= 27
⇒ 3x= 27+ 1 (inverse operation)
⇒ 3x= 28
⇒ x= 28/3 (inverse operation)
⇒ x= (27+1)/3
⇒ x= 27/3+ 1/3
⇒ x= 9+ 1/3
⇒ x= 9 1/3

Final answer: x= 9 1/3.
