Andrew and Blake had equal amount of money at first. Andrew then spent $10 while Blake was given another $56. In the end, Andrew has one-third as much money as Blake. How much money did Andrew have at first?

amount at beginning
Andrew = Blake = x

after eventful day:
Andrew has x - 10
Blake has x + 56

Andrew has one-third as much money as Blake
--->
x - 10 = (1/3)(x+56)
multiply by 3
3x - 30 = x + 56
2x = 86
x = 43
