(470-х) :3+65=172

To solve the expression (470-х) :3+65=172, we need to follow the order of operations, which is often remembered using the acronym PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction).

Let's break down the expression step by step:

1. Start with the parentheses: (470-х) Since there is no specific value given for "х," we cannot simplify this further.

2. Next, divide the expression from step 1 by 3: (470-х) : 3 Again, we cannot simplify this further without the value of "х."

3. Lastly, add 65 to the expression from step 2: (470-х) : 3 + 65 Since we couldn't simplify the expression before, we cannot simplify it further.

So, the expression can be written as (470-х) : 3 + 65 = (470-х) : 3 + 65.
