let
s = the money Simon saved
d = the money Carly saved
Simon saved $63.35 more than her brother Dan and $37.50 less than her sister Carly. Carly saved $127.75.
s = 63.35 + d
s = 127.75 - 37.50
s = $90.25
plug s = $90.25 into s = 63.35 + d:
90.25 = 63.35 + d
63.35 + d = 90.25
d = 90.25 - 63.35
d = $26.90
Simon saved $90.25.
Dan saved $26.90.
