Sarah and bryan went shopping and spend a total of $47.50. bryan spends $15.50 less than was sarah spent. how much did bryan spend?

Hey there,
Sarah= $x
Bryan = $x - $15.50
$x + $x - $ 15.50 = $47.50
$x + $x = $47.50 + $15.50
$2x = $63
$x = $63 / 2 
     = $31.50
Bryan = $31.50 - $15.50
           = $16

Hope this helps :))
