b = Brent´s books
t = Timmy´s books
Brent has 6 times as many books as Timmy means:
b = 6 t
If Timmy had 45 more books, the two boys would have exactly the same amount means:
t + 45 = b
Replace b by 6 t in this equation.
t + 45 = 6 t
Subtract t to both sides
45 = 5 t
45 / 5 = t
9 = t
t = 9
b = 6 t = 6 ∙ 9 = 54
Brent have 54 books.
Brent has 6 times as many books as Timmy. If Timmy had 45 more books, the two boys would have exactly the same amount. How many books does Brent have?
