Step-by-step explanation:
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.
Answer:
x = 3, y = -4
Explanations:
The given system of linear equations is:

The graph representing the equations is plotted below:

The point where both lines intersect is the solution to the system of equations.
The lines intersect at the point (3, -4), therefore, (3, -4) is the solution to the system of equations
