Question

Write an algebraic expression to represent the phrase "The difference between tow times b and eleven"

Answer 1

2b-11
b represents the unknown number.
Since it says ‘two times b’ before eleven, then the 2b comes first in the expression.

Answer 2

Answer: 2b - 11

======================================

Step-by-step explanation

b = some unknown number (think of it as a placeholder or a box to put the number inside)

2*b = two times the unknown number b

2*b - 11 = difference of two times b and eleven

side note: 2*b is the same as 2b. The multiplication symbol is often dropped to save space.
