Answer 1

Too bad you didn't bother to show your work.
or use parentheses when necessary
#1 (y-5) / 3 =1
y-5 = 3
y = 8

#2. nope - you need to divide by 6, not multiply
#3. nope - watch those +/- signs
#4. nope - again, exactly backwards
9a - b - 2a - 10b
9a - 2a - b - 10b
now, 9-2 = 7, so you get
7a - 11b
#5. correct, assuming you meant 5(x + 10) + x
#6 appears correct
#7 ok
#8 nope - how did you arrive at that answer?
