(a) 2/3
(b) 3/5
(C) 5
(d) None of these​

Answer 1

Answer:

$15(y - 4) - 2(y - 9) + 5(y + 6) = 0 \\ \\ = > 15y - 60 - 2y + 18 + 5y + 30 = 0 \\ \\ = > 15y - 2y + 5y - 60 + 18 + 30 = 0 \\ \\ = > 18y - 42 + 30 = 0 \\ \\ = > 18y - 12 = 0 \\ \\ = > 18y = 12 \\ \\ = > y = \frac{12}{18} \\ \\ = > y = \frac{4}{6} \\ \\ = > y = \frac{2}{3}$
