Recall, a function will have no x-repeats, now if it has any, is not a function then, is just a relation, check the picture below.
Answer:
x = 8
Step-by-step explanation:
Since AB and BC combined would create the total amount of distance between AC your equation becomes 2x+1+3x = 41. 2x and 3x share the same variable therefore you can add them together which then makes the equation 5x+1 = 41. Now the equation can be solved, subtract 1 from both sides which gives you 5x = 40. From there you divide 5 from both sides which leaves you with 8 as the value of x.
