Answer:

3n + 5

Step-by-step explanation:

3n + 7 - 2

3n is a variable.

7 and 2 are numbers.

Variables can be added with variables.

If variables are added with numbers, it remains constant ( and vice - versa ),

That is.

3n + 7 = 3n + 7

When the value of n is given, then the result of " 3n + 7 " will be a number.

In this question, the value of n is not given.

Numbers can be added or subtracted with numbers. The result will be a number.

7 - 2 = 5

So,

the answer is 3n + 5

Answer:

3n+5

Step-by-step explanation:

Like terms are the terms that can be added together, in this example, 7 and -2. There aren't any other like terms so if you add them together, the answer would be 3n+5.

How do i solve 12×+9=10×1

Answer:

Step-by-step explanation:

Unfortunately, your " 12×+9=10×1 " can be interpreted in more than one way. The symbol " × " should be used ONLY to indicate multiplication. Thus, " 12× " reads as ' 12x.' Then we have: 12x + 9 = 10. Unsure of what you meant by " 10×1". So I will treat your "10×1" as simply '10.'

Then we have 12x + 9 = 10, which reduces to 12x = 1 if we subtract 9 from both sides.

12x = 1 yields x = 1/12.

If this is not the result you expected, please go back to the original problem and share it as accurately as you can.
