John claims the following two expressions are equivalent. - 215y - 3) = - 10y - 6
John's work in determining an expression equivalent to the first expression is shown below.
- 2/5y - 3)
= (-2x5y) - (-2x - 3)
= - 10y-6
Which statement explains why John's claim is incorrect?
He should have subtracted (-2 * 3) resulting in the expression–10y + 6.
He should have only multiplied 3 by -2 resulting in the expression 5y - 6.
He should have only multiplied Sy by -2 resulting in the expression-10y - 3.
He should have only multiplied 3 by -2 and subtracted (-2 * 3) resulting in the expression 5y + 6.
