Part B

Brittany’s brother, Nate, is two years younger than Brittany. Write an equation for Nate’s age, n, in terms of Brittany’s age, b.
Part C

Rewrite the expression from Part B to get the variable b alone on one side of the equation. (This is also called isolating b.)
Part D

Substitute the value of b from Part C into the inequality you found in Part A.
Part E

Solve the inequalities from parts A and D for the variables b and n, respectively.
