Answer:

x = 92/7 , y= 36/7

Step-by-step explanation:

 \frac{x}{4}  +  \frac{y}{3}  = 5 \\ 3x + 4y = 60...........(1) \\  \frac{x}{2}  -  \frac{y}{9}  = 6 \\ 9x - 2y = 108 ..........(2) \\ multiply \: by \: eq(2) \times 2 \\  \\ 18x - 4y = 216..........(3) \\ 3x + 4y = 60.......(1) \\ add \: eq \: (1) \: nd \: (2 \\ 21x = 276 \\ x =  \frac{92}{7}  \\ take \: x \: vlues \: in \: eq(1) \\ 3 \times  \frac{92}{7}  + 4y = 60 \\ 4y = 60 -  \frac{276}{7}  \\4 y =  \frac{144}{7}  \\ y =  \frac{144}{28}  \\ y =  \frac{36}{7}
