Many people find this to be a complicated topic.
Please try to follow my steps as I solve the problem
and answer your question. I'll go slow.

The absolute value of +91 is +91 .
Was there anything there that you couldn't follow ?
Answer: 72
We can use ratios
117 inches / 13 inches = 9
The corn cast shadow is 9 times bigger than the example we are given.
9 * 8 = <u><em>72</em></u>
Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.
y=7x-8
y=5x-2
7x-8=5x-2
+8 +8
-----------------
7x=5x+6
-5x -5x
----------------
2x=6
/2 /2
-----------
x=3
y=7x-8
y=21-8
y=13
Part B) The lines will intersect at point (3, 13), because idk it just makes sense
