Question

Which expression is not equivalent to 1/3(9y-3)-2y?

Answer 1

Explanation:

Simplify 1/3(9y-3) - 2y as : 3y - 1 - 2y = y - 1

Expression 1 : 3y - 1 - 2y, can be simplified as y-1 => Equivalent
Expression 2 : 3y + 3 - 2y = y + 3 => Not equivalent
Expression 3 : y - 1 => Equivalent
Expression 4 : 1/3(9y) + 1/3(-3) - 2y = 3y - 1 - 2y = y-1 => Equivalent

So, the answer is the second expression.
