Simplify the expression

4b + 9 + 3b – 5b – 5 + b

• 2b + 4

• 2b – 4

• 3b – 4

• 3b + 4

Simplify the expression 7b + 4t + 3t + 4c – 9t + c – 7k – b + 4b

• 10b – 2t + 5c – 7k

• 10b + 2t + 5c – 7k

• 10b – 2t + 5c + 7k

• None of the above

Simplify the expression

10y – y + 5y + 3y – 6y

• 10 + 2y

• 11y

• 12y

• None of the above
