18 = 2x +4

Subtract 4 from each side:

14 = 2x

divide both sides by 2:

X = 14/2 = 7 dollars per hour

I believe it's 18=2x+4

It's $4 MORE than TWICE the amount. Add $4 to the 2. Assuming 'x' is used to represent hours. 18 is the total.

Now, the internship pays $7 an hour. How do I know that?

$18-$4=$14

The $4 more

14/2=7

TWICE as much
