so you just need to replace the letters with numbers your given. If theres a number next to a bracket like this 3(blahblah) you have to times 3 by everything in the bracket, in this case 3 times blahblah... 3blahblah

if you have two things in the bracket then you times the 3 by both like this 3(blah1 + blah2) = 3blah1 +3blah2
