A star the designation HD 12929 in the constellation Aries is approximately 60 light years from Earth's sun. this star could also be said the be how far from earth's sun?

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
