Quizplus · Accepted Answer

"Twice a number" can be represented as 2x, and "the difference of...and 10" means to subtract 10 from the expression. Therefore, we get the equation 2x - 10 = 14. "Twice a number" can be represented as 2x. 
So, "the difference of twice a number and 10" is 2x - 10. 
And the problem states that this is equal to 14. 
Therefore, the equation becomes 2x - 10 = 14.
