Answer:
Explanation:
The expression for the sequence of operations "3 decreased by the difference of 4 and y" can be written as: 3 - (4 - y) Let's break down the expression step by step: 1. We start with the difference of 4 and y, which is represented as (4 - y). 2. Then, we decrease 3 by the result of step 1, which is represented as 3 - (4 - y). To simplify this expression further, we can distribute the negative sign inside the parentheses: 3 - 4 + y Now, we can combine like terms: -1 + y Therefore, the simplified expression for the given sequence of operations "3 decreased by the difference of 4 and y" is -1 + y.
