BBSJSSJJSNSNNSOAOOALAKA
X=any number
x is( greater than sign) (and then a line at the bottom of the greater or less than sign) x
it would be like this
x is greater than or equal to x
or
x is less than or equal to x
N=d-2
q=n+d =>q=(d-2)=q=2d-2
25q+5n+10d=525
replace q and n with d
25(2d-2) +5(d-2)+10d=525
50d-50+5d-10+10d=525
65d=585
d=9
n=7
q=16
