Question 1134432
<br>
From your first equation,<br>
{{{B+T+L= $14685 + T + L = $16070}}}  -->  {{{T + L = 1385}}}<br>
Similarly, from your other two equations, you can get values for A+L and A+T.<br>
Then the trick is to add the three resulting equations; that will give you the value of 2A+2L+2T.  Divide by 2 to find the value of A+L+T.  Then compare that value to each of the equations you have for the sum of two of the variables to find the value of each individual variable.<br>
Probably sounds confusing if you haven't done it before; here's an example.<br><pre>
        A+B = 34
        A+C = 53
        B+C = 61
 ----------------
  2A+2B+2C = 148

  A+B+C = 148/2 = 74

  A = (A+B+C)-(B+C) = 74-61 = 13
  B = (A+B+C)-(A+C) = 74-53 = 21
  C = (A+B+C)-(A+B) = 74-34 = 40</pre><br>
