網頁【解析】(1)3x+y=3;4x-y=11. ①①.②+②,得7x=14,解得x=2.把x=2代人 ① ,得6+y=3,解得y=-3.所以原方程组的解是x=2;y=-3. (2)x+2y=0;3x+4y=6. ①.②① 2-② ,得-x=—6,解得x=6.把x=6代人 ① ,得6+2y=0,解得y=-3.所以原方程组的解为(3)2x-3y=-5;3x+2y=12. ,①①*2+②*3 ,得13x=26,解得x=2.② 把x=2代人②,得y=3.所以原方程组的解是x=2;y=3., 網頁We will solve the given equation, x² + y² ‒ 12x ‒ 4y = 0, by first identifying what type of curve it represents, then convert the given equation to a much more useful, informative form, …
