Order of operations tells you how to simplify this:
7a - 3(2a-4)
Nothing between the 3 and the parentheses indicate implied multiplication.
Inside the parentheses is a binomial that cannot be simplified much, but it can be factored if you wish to add more steps.
Using the law of distribution 7a - 6a + 12
simplifying = a + 12
Also, this is not an equation, it is a statement.
