Answer 1

$\left \{ {{ \frac{3}{4} x - \frac{1}{6} y = 1} \atop {3x - \frac{2}{3} y = 4}} \right. \\ \left \{ {{x = \frac{4}{3} + \frac{2}{9} y} \atop {3x - \frac{2}{3} y = 4}} \right. \\ 3( \frac{4}{3} + \frac{2}{9} y) - \frac{2}{3} y = 4 \\ y∈R \\ \boldsymbol{( \frac{4}{3} + \frac{2}{9}y,y) \: , \: y ∈R }$
