$\huge\underline{ \underline{ \red{your \: \: answer}}}$

Step-by-step explanation:

$\sf\red{x - 4 = 3 - - - - - - - (1)} \\ \\ \sf\red{2x + y = 6- - - - - - - (2)} \\ \\ \sf\red{(1) = x = 7 - - - - - - - - (3)} \\ \\ \sf\red{value \: of \: x \: put \:in \: (2)} \\ \\ \sf\red{ = > 2 \times 7 + y = 6} \\ \\ \sf\red{ = > y = 6 - 14} \\ \\ \sf\red{ = > y = - 8} \\ \\ \sf\red{x = 7 \: \: \: y = - 8} \\ \\ \large\boxed{ \fcolorbox{violet}{yellow}{hope \: it \: help \: you} }$
