220 miles is how much Mrs. Johnson drove. because . . .

2x+x=330
2x is twice the amount of Mr. Johnson which equals Mrs. Johnson.
The plain "x" is how much Mr. Johnson drove. 

2x+x= 3x
3x=330- x=110

If 'x' is how much Mr. Johnson drove then we multiply that by two to get 220.

Damm [24]

Answer:

dependent

Step-by-step explanation:

The given system is :

15x-18=3y

5x=y+6

Rewrite the equations in standard form to get:

15x-3y=18

5x-y=6

Multiply the bottom equation by 3.

15x-3y=18

15x-3y=18

Sub both equations:

0-0=0

0=0

We got an identity

The system is dependent  because there are infinitely many solutions
