-5x=60
The first thing we want to do is to divide -5 on both sides. We do this because -5x, is the same as -5 times x and we want to do the inverse of that.
After we divide on both sides, we get x=60/-5
We know that 60 divided by -5 is -12.
Therefore our answer is: x=-12

5= n + 2
We always want to get the variable to be alone, so if we subtract by 5 we would be doing the opposite of getting the variable alone. Although, if we subtract by 2 on both sides, we would get the variable alone and the answer would be 3=n
Therefore our answer is: False

2(x-7)
By looking at this question, we see x being subtracted by 7. Then we see that 2 is being multiplied to that.
Therefore our answer is: C

The product of a number and 4 increased by 8
In these types of questions, it's smart to break it up. We will start with the product of a number and 4. We know that a number is a variable and if we look at the multiple choice answers we can see that the variable they chose to use is n. We also know that a product is when numbers get multiplied. So that means 4 and n get multiplied which turns into 4n.
For the other part of the problem, we know that increased by 8 means added my 8. Now that we got our answers, we put then together.
Therefore our answer is: A 4n+8
