We have three equations that we can use for this problem.

<span>X1 − X3 = 35</span>

<span> <span>X2 − X1 = 50</span> <span> <span>X3 – X2 = 15</span> To solve for C and A. We’ll take the first equation and put 23 for X1. <span>X1 − X3 = 35</span> <span> <span>23 − X3 = 35</span> <span> <span>−X3 = 35 - 23</span> <span>−X3 = 12 The estimated traffic flow for C and A is 12 cars per hour.</span> Now, to solve for B and C, we’ll take the second equation and put 23 for X1 as well. <span>X2−X1=50</span> <span> <span>X2− (23) =50</span> <span> <span>X2 = 50 + 23</span> X2 = 73 The estimated traffic flow for B and C is 73 cars per hour.   <span> </span></span></span></span></span></span></span>
