It will be 3 weeks because if you divide 7/2,100 it will become to be 3weeks
79.21-69.91=9.3 so the answer is 79.21
Hope this helps!!
Since we have to solve this system graphically, we'll have to draw both lines.
To draw a line, simply build a little tables with two x,y values: for the first line we have

So, you can draw the points (0,3) and (1,2), connect them, and you'll have the graph of the line 
For the second line we have

So, you can draw the points (0,5) and (1,6), connect them, and you'll have the graph of the line 
Finally, we have to check where the two lines cross. If your drawing is accurate enough, you'll see that the point you're looking for is (-1, 4)
-19 ÷ 7 = -2.7142857142857143
