twice the difference of a number and 11
The difference of a number and eleven is x-11 Twice that difference is 2(x-11)
Thus, since a = 33, b = 11, your two numbers are 11 and 33
Well the number we don't know can be represented by x. Twice the difference of a number and 11 is that same thing as taking the difference between x and 11 and then multiplying by 2. So we have \[2(x-11)\] You can distribute 2 to obtain\[2x-22\]
