d dimes and q quarters
d+q = 139
10 d + 25 q = 2395
I would solve the first equation for d = (139  q)
then substitute that value for d in the second equation
however you could just as well multiply the first equation, both sides, all terms, by ten. the if you subtract the first equation from the second, you eliminate d.
