sorry. x does equal 1/7y - 15. but if you only spend 210 minutes practicing that one week, it is impossible for you to practice 245 or 315 minutes on the new song.
a. y = 7(15 + x) y = 105 + 7x y - 105 = 7x 1/7y - 105/7 = x X DOES NOT EQUAL 1/7y - 15. You didn't distribute the 7 to 15. Remember to distribute to all on the equation, not just the x! b. 210 = 105 + 7x 105 = 7x x = 105/7 = 15 minutes practicing new song
to anon at 9:19 PM: yours is wrong because you did not divide ALL of the equation by 3.
h + p = 3(k-8) h + p = 3k -24 h + p + 24 = 3k 1/3h + 1/3p + 8 = k
