The solution to any system graphically can be found where the 2 graphs intersect. These two graphs intersect at the point (0, 2).
The information we know:
1 week = 134 inches
x = 714
What I did was, I divided 714 by 134 to find the amount of weeks:

So, from the equation, basically, in 6 weeks (actually 5.3 weeks) the plant will grow 714 inches long

21 + 15 = 36
36 x 3 = 108
Their father donated $108 to charity
Substitute 3 for x, so
4(3) + 6
12 + 6
