4x-3y= -3
-10x-6y=3

Answer 1

$left { {{4x-3y=-3} atop {-10x-6y=3}} right.$
$left { {{-3y=-3-4x} atop {10x+6y=-3}} right.$
$left { {{3y=4x+3} atop {10x+2(4x+3)=-3}} right.$
$left { {{3y=4x+3} atop {10x+8x+6=-3}} right.$
$left { {{3y=4x+3} atop {18x=-9}} right.$
$left { {{3y=4x+3} atop {x=- frac{1}{2} }} right.$
$left { {{3y=-2+3} atop {x=- frac{1}{2} }} right.$
$left { {{y= frac{1}{3} } atop {x=- frac{1}{2} }} right.$
