To solve this problem, first we need to define that the number is "x".
Then, we define what twice that number is, which would be
We decrease that 2x by 2:
And this would be equal to 14:
That would be the equation that represents the problem.
To solve that equation...
We add +2 to both sides of the equation:
and we divide both sides by 2:
Answer:
the equation is: 2x - 2 = 14
and the value of x is: x =8
