hey buddy,

here is your ans..

Answer:

\frac{3x - y + 7}{11 }  + 2 = 10 \\  \frac{3x - y + 7 + 22}{11}  = 10 \\ 3x - y + 29 = 10  \times  11 \\ 3x - y = 110 - 29 \\ 3x - y = 81 \:  \:  \: ...........(1) \\  x =  \frac{8 + y}{3} \:  \: .................(3)\\  \\  \frac{2y  - x + 11}{7}  = 10 \\ 2y - x = 70 - 11 \\ 2y - x = 59 \:  \:  \:  \: ................(2)\: from \: first \: equation \: find \: x \\   \\ put \: n \: (2) \: equation \\ 2y -  (\frac{8 + y}{3} ) = 59 \\  \frac{6y - 8 + y}{3}  = 59 \\ 7y - 8 = 177 \\ 7y = 177 + 8 \\ 7y = 185 \\ y =  \frac{185}{7}  \\ put \: y \: in(3) \: equatio \\ x =  \frac{8 +  \frac{185}{7} }{3}  \\ x =  \frac{241}{21}

I hope it helps you

thank you

have a great day..
