This equation is asking you to combine like terms, which are terms with the same variable and same exponent. The terms in this equation that have the same variable and exponent are 3/2y and -3/2y. When you add these two terms together, they cancel each other out, because 3/2y - 3/2y = 0. So when you combine the like terms, the equation becomes 0 + 4 = 4. Therefore the answer to the equation is 4.
