An expression in simplest form for the total number of brads in her bracelet design

Answer to Problem 13GP
The expression is
Explanation of Solution
Given information:
Marena is using a certain number of blue beads in a bracelet design and she will use 7 more red bead than blue beads
Concept used: YEARS MORE THAN
Rules of Addition/ Subtraction:
- Two numbers with similar sign always get added and the resulting number will carry the similar sign.
- Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.
Rules of Multiplication/ Division:
- The product/quotient of two similar sign numbers is always positive.
- The product/quotient of two numbers with opposite signs is always negative.
Calculation:
In order to find the given expression, let b be the blue beads
Then red beads are 7 more than the blue ones so and the expression will be shown below
Thus, the expression is
