Answer:


X = 6

Explanation:


2x + 12 = 14


-12
-12

---------------------


(2x)/(2) = (12)/(2) =
x = 6

1. Set the equation up.

2. isolate the x from 2x then do the opposite of 12 to -12

3. subtract from 14

4. make proportion.

5. divide both sides.

6.

Answer:

2x+12=24

first you subtract 12 from both sides

2x+12=24

-12. -12

The 12-12 should cancel itself, the rest of the equation you bring down to get

2x=12 (because 24-12=12)


Now you have 2x=12.
you then divide 2x by both sides.

2x=12

/2x=/2x

The 2x/2x cancels itself out so you then solve for 12/2x.

For this you just divide 12/2 which is 6!

x= 6 is your final answer.
to check this equation you can plug your number back into x to see if it is true! 2(6)+12=24.
6 times 2 is 12 and 12+12 is 24 so your answer (6) is true!


hope this helps! :D
