If 2x +3y = 30 and (x+y)/y = 11/8, then find the value of 5y + 6x
Answers:
A) 76  B) 58  C) 99  D) 26  E) 17
Explanation:   The given equations are :   2x + 3y = 30 --------- (i)   and, (x+y)/y = 11/8   8x + 8y = 11y   8x – 3y =0 ----(ii)   Adding (i) &amp; (ii), we get : 10 x = 30 or x = 3.   Put x = 3 in (i), we get : y = 8   Therefore, 5y + 6x = (5 * 8 + 6 * 3) = 40 + 18=
