A number added to itself seven additional times is fourteen more than the number. What is the number?

a. 9/14B. 2C. 7D.-2

Let's make an equation.

X will be the number.

When we are adding a number to itself seven additional times, we are basically multiplying the number.

x+x+x+x+x+x+x+x=8x

8x=x+14

Let's subtract x from both sides.

7x=14

Let's divide.

14:7=2=x

So, B. 2.
