Question

Haley read three less than twice as many books as her brother did last summer. haley read five books.which equation could you use to find how many books her brother read (b)?

Answer 1

Your answer would be 2b-3=5
The 2 stands for the "twice as many"
The b stands for her brother.
The 3 stands for the "3 less books"
And the 5 stands for Haley's total.

I hope this helps!

Answer 2

2b - 3 = 5

Explanation:

If her brother read b number of books last summer, twice the number of books her brother read

= 2b

three less than twice as many books as her brother read

= 2b - 3

If haley read five books and it is same as three less than twice as many books as her brother last summer, then

2b - 3 = 5
