Question

Twenty-one more than three times a number is equal to the difference between 46 and twice the number. Find the number.

Answer 1

Answer: The number is =5

Step-by-step explanation:

21  +                  3X                              =         ("Difference means subtract.)                           2X

Twenty-one more than three times a number is equal to the difference between 46 and twice the number

Then write the proper equation:     21+3x= 46-2x.

 

Next get rid of the smaller "x" so 3x+2x=46-25

solve X

5x=25

x=5
