$x = \frac{37}{22}, y = - \frac{22}{21}$ $x=37/22,y=-22/21$

Explanation:

Multiplying the second equation by $- 3$ $-3$ and adding to the first
we get
$y = - \frac{22}{21}$ $y=-22/21$
plugging this in the second equation we get
$x = \frac{1}{2} (7 - \frac{110}{21})$ $x=1/2(7-110/21)$
$x = \frac{37}{42}$ $x=37/42$
