解方程组2x-3y=10,-4x+y=-5今天现在,要对,

解方程组,x+y/2=3x-2y=10+6x+y/4, 解方程组3x+5(x+y)=2 3y-2(x+y)=4 解方程组｛ 3x-4y(x-y)=3 { 2x-3y=1 解方程组x+y/3=x-y/4 2x+3y=11 解方程组 y=2x x+y=3 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。 已知方程组{3x+4y=10 4x+3y=-2,不解方程组则x+y= 解方程组:(x+3)(y-2)=(x-3)(y+10),(x+1)(y+3)=(x-2)(y+12) 解方程组;x+y/2=x-y/3=6 4(x+y)-3(x-y)=-20 解方程组 2x+y(y-2x)=9 (x+y)(x+y-3)=10十万火急!求解! 解方程组2(x-y)/3-x+y/4=-1 6(x-y)-4(2x-y)=16 解方程组：2(x-y)/3-x+y/4=-1 ,6(x+y)-4(2x-y)=16 解方程组:2(x +y)-3(x-y)=3;4(x+ y)+ 3（x-y）=15 解方程组 4(x+y)-(2x-y)=14 ,3(x+y)-2(2x-y)=8 3/(X-Y)+10/(X+Y)=-5 2/(X-Y)-15/(X+Y)=1 解分式方程组 解二元一次方程组3(x+y)-4(x-y)=4 x+y/2+x-y/6=1 解方程组3(x+y)-4(x-y)=4和(x+y)/2+(x-y)/6=1kkkkkkkk
