 The number is 14   ,  look into the steps for more explanations.

Step-by-step explanation:

Twice the sum of a number and seven  is three times the number .  

in this case we will represent that number  by the variable x.

The sum of x and 7  is      x+7  

Twice that will be     2(x +7)  

That has to equation  three times the number which will make it

2(x+7) = 3x    Now solve for x to find the number  by distributing

2x + 14 = 3x           Subtract 2x from both sides

 2x          -2x

 14 = 1x              Divide both sides by 1

x = 14
