Tammy completed the following steps to simplify the expression
-5x²y - 3xy² - 2(4y + 2) - 2.5x²y.
-5x²y - 3xy² - 2(4y) + 2(2) - 2.5x²y
-5x²y - 3xy² - 8y + 4 - 2.5x²y
(-5x²y - 3xy² - 2.5x²y) - 8y + 4
(-5 - 3 - 2.5)x²y - 8y + 4
-10.5x²y - 8y + 4
Explain why Tammy's solution is incorrect. Then show how to correctly simplify the expression.
