Answer:  The number is 1.2

Step-by-step explanation:

In this situation we will represent the number by x  .  

3 times that number will  give us the expression  3x  and the sum of 3x and 14 will be  3x + 14  

It says that has to equal  the difference between twenty and two times the number which can be represented by the expression,  20 - 2x

3x + 14 = 20 - 2x    Now solve for x to find the number

    -14        -14

3x = 6 - 2x

+2x       +2x

  5x = 6  

x = 1.2
