Question:

Simplify this expression: 2x + 3(x + 5)

In this problem, we need to follow the order of operations. Some schools use PEMDAS or BEDMAS (or a variation of the sort) to help you remember the order of operations. PEMDAS means Parenthesis, Exponent, Multiplication or Division (which ever comes first from left to right), and Addition or Subtraction (which ever comes first from left to right). According to the order of operations, we need to get rid of the parenthesis first. In order to do that, we need to use the Distributive Property, which states: a(b+c) = ab + ac This is our original expression: 2x + 3(x + 5) This is after we use the distributive property on the 3(x + 5) part: 2x + (3)(x) + (3)(5) 2x + 3x + 15 Now, next down the list is addition. Here, we can see that we can combine the 2x and the 3x because they have the same degree (or "last names"): 5x + 15 Since there are no more terms with the same degree, 5x + 15 is in its simpliest form and is, therefore, our answer.
