解方程组3x+10y=14,10x+15y=32
解方程组 10(x-y)=3(x+y)+15 6(x+y)=4(2x-y)+16
解方程组x+y=15 (x+15%x+y+10%y)=17
一次方程组x=y+3 (10y+x)+(10x+y)=99 怎么解
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x+y/6+x-y/10=3,x+y/6+y-x/10=-1
解方程组:(x+3)(y-2)=(x-3)(y+10),(x+1)(y+3)=(x-2)(y+12)
10/x+y+3/x-y=-5 15/x+y-2/x-y=-1(用换元法解此方程组)
解方程组 2x+y(y-2x)=9 (x+y)(x+y-3)=10
解方程组:x/2+y/3=1 x*20%+y*30%=14*10%
9x+2y=15,3x+4y=10解方程组
xy=(x-10)(y+1) xy=(x-15)(y+3) 解方程组.
