Answer 1

Hi Dorothy,

The trick to solving this question is converting it to an algebraic equation:

Double the number increased by one is 23. What is the number?

2n

Double the number increased by one is 23. What is the number?

2n + 1

Double the number increased by one is 23. What is the number?

2n + 1 = 23

To solve, start by subtracting 1 from both sides of the equation.

2n + 1 - 1 = 23 - 1

I won't give away the answer by continuing to solve it from there, but you can probably apply your algebra to solving the rest of the equation.
