This problem is asking you to use the Distributive Property of Multiplication to simplify the expression. To do this, combine like term inside the parenthesis and then multiply each term outside the parenthesis (just 2 in this case) by each term inside the parenthesis.
First, simplify the expression inside the parenthesis by combining like terms.
2(14x - 3y + 28x + 12.2 - 5y - 17.5)
2[14x + 28x + (-3y) + (-5y) + 12.2 + (-17.5)]
2(42x - 8y - 5.3)
Now we can multiply each term inside the parenthesis by 2.
(2)(42x) + (2)(-8y) + (2)(-5.3)
84x - 16y - 10.6
Hope this helps!
