Hope this will help you :D

Step-by-step explanation:

Twice a number decreased by 2 is 40. What is the number ?

Equation: 2x - 2 = 40

Solution: 2x - 2 = 40

               2x - 2 = 40 + 2

               2x      = 40 + 2

                       

               2x = 42

               2   = 2

               X = 21                                                      

               

Check: 2x - 2 = 40

            2(21) - 2 = 40                                                        

            42 - 2 = 40

            40 = 40

Therefore, the number is 40
