Answer 2

$2x + 3y = 10...(i) \\ 3x - y = 4...(ii) \\ from \: equation(ii) \\ 3x - y = 4 \\ - y = - 3x + 4\\ y = - ( - 3x - 4) \\y = 3x + 4 \\ putting \: (y = 3x + 4 )\: in \: equation \: (i) \\ 2x + 3(3x + 4) = 10 \\ 2x + 9x + 12 = 10 \\ 11x = 10 - 12 \\ 11x = - 2 \\ x = \frac{ - 2}{11} . \\ now \: putting( x = \frac{ - 2}{11}) \:in \: equation \: (ii) \\ 3 \times \frac{ - 2}{11} - y = 4 \\ \frac{ - 6}{11} - y = 4 \\ - y = \frac{4}{1} + \frac{6}{11} \\ - y = \frac{44 + 6}{11} \\ - y = \frac{50}{11} \\ y = \frac{ - 50}{11} .$

$so.. \\ x = \frac{ - 2}{11} \\ y = \frac{ - 50}{11} .$

hope it helps !!
