    Answer Check

    Could you please help to see if this correct, much appreciated. Not sure whether it is 15 + or - 22!

    3(y - 4)- 2(5 - 6y)

    3 y, 3 4, 2 5, 2 6y

    3y + 12 + 10 + 12y

    = 15y 22

    I don't know what your notation is supposed to signify, but:

    3(y - 4)- 2(5 - 6y)=[3\times y-3\times 4]-[2\times 5-2\times 6 \times y]=3y-12-10+12y=15y-22
