$2x+4 = 14\\2x+4-4 = 14-4\\2x = 10$

Dividing both sides by 2

$\frac{2x}{2} = \frac{10}{2}\\x = 5$

Answer:

6 5/8

Step-by-step explanation:

You need to add 2 3/4 and 3 7/8

2 3/4 as an improper fraction is 11/4 and 3 7/8 as an improper fraction 31/8

To add them you need to have common denominators

So you multiply 11/4 by 2/2 which is 22/8

Now you can add them

22/8+31/8 = 53/8

53/8 = 6 5/8
