Question

Four more than twice a number x is 12. Write an equation that represents this situation. Determine the number x

Answer 1

2x+4=12

x=4

Explanation:

Let's look at the way that this question is written in order to write the equation

"Four more than" this means that we need to add 4 to the next thing that is listed.

"Twice a number x" means 2x

Combining the last two gives us 2x+4

"Is 12" means =12

Combining everything gives us

2x+4=12

Now we can solve for x

`2x+4=12\\\\2x=8\\\\x=4`
