Answer 2

Answer:

$(x,y)=(2,5)$

Step-by-step explanation:

Multiply a constant to make the equation simple.

$\left \{ {{11x-9y=-23} \atop {45x+28y=230}} \right.$

Subtract $x$, then solve for $y$.

$465x+308y=2530$

$465x-405y=-1035$

$713y=3565$

∴$y=5$

Substitute $y=5$.

$11x=-23+45$

$11x=22$

∴$x=2$
