John claims the following two expressions are equivalent -2(5y 3) = 10y - 6
John's work in determining an expression equivalent to the first expression is shown below,
2(5y 3)
+(25)(-2% -3)
10y6
Which statement explains why John's olaim is incorrect?

A He should have subtracted (-2 * 3) resulting in the expression 107 * 6.

B He should have only multiplied 3 by 2 resulting in the expression by - 6

C He should have only multiplied Sy by 2 resulting in the expression - 1043

D He should have only multiplied 3 by 2 and subtracted (23) resulting in the expression Sy + 6
