I have no clue what the answer is and the final is this afternoon! Please respond quick!
(7/10) (d - 5/6 ) = 7 multiply both sides by 10/7
d - 5/6 = 10 add 5/6 to both sides
d = 10 + 5/6 = 65/6
5c / 4 - 2c / 3 = 7/10 multiply through by the LCM of 4, 3 and 10 = 60
75c - 40c = 42
35c = 42 divide both sides by 35
c = 42/35 = 6/5
