Question

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

a.9/14B.2C.7D.–2

Answer 1

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.
