解方程组：3x+6y=10 6x+3y=8求根号下xy的值

解方程组,x+y/2=3x-2y=10+6x+y/4, 用加减法解方程组:{(x+y)/6+(x-y)/10=3 (x+y)/6+(y-x)/10=-1 解方程组（三分之x+y）+y=6,3(x+y)-y=24 解方程组：｛4x+5(x-y)=30,4y-3(x-y)=6 解方程组 x=3y-6 0.8(x+y)=x+y-13.6 解方程组x+y/6+x-y/10=3,x+y/6+y-x/10=-1x+y/6+x-y/10=3 ①x+y/6+y-x/10=-1 ② 解方程组 10（x-y)=3(x+y)+15 6(x+y)=4(2x-y)+1610（x-y)=3(x+y)+156(x+y)=4(2x-y)+16 解方程组 10（x-y)=3(x+y)+15 6(x+y)=4(2x-y)+1610（x-y)=3(x+y)+156(x+y)=4(2x-y)+16分开的。 解方程组;x+y/2=x-y/3=6 4(x+y)-3(x-y)=-20 解方程组⑴(x+y)/2-(x-y)/3=6,⑵3(x+y)=4(x-y) 3/x+y+2/x-y=6,3（x+y)-2(x-y)=28解这个方程组 解方程组 x-y/3-x+y/4=2 x-y/6-x+y/8=3 解方程组4（x+y)-3(x-y)=14;(x+y)/2+(x+y)/3=6 解联立方程组 x/x+y=5/8 x/x+y+6=2/3 2(x+y)-3(x-y)=1 6(x+y)+7(x-y)=51 解方程组 解方程组 X+Y/2+X-Y/3=6 4[X+Y]-5[X-Y]=2 解方程组﹛2(x+y)-3(x-y)=1 6(x+y)+7(x-y)=51 解二元一次方程组3(x+y)-4(x-y)=4 x+y/2+x-y/6=1
