heres what we know
X=2006 goals
y= 2007 goals
497 = X +Y which can be arranged to be y= 497 - x
y= 37 + x
soooo..
we make the y equations equal to each other
37 + x = 497 - x
2x = 460
x= 230
now plug that back into the original equation to check
y = 37 + (230)
y = 267
so in 2006 (remember x represents 2006 goals) she made 230 goals
