Hi there

first ignore the number 2 as if it was there

Then try to open that bracket containing ( 2 - 3b) with the number 9

so you will multiply 2 by 9 that is 9*2 and as well as multiplying -3b by 9 that is, 9*-3b

now you have 2 + 18 -27b

solve that 2 + 18

what ever you get - 27b

that is (2+18) - 27b
