解方程组 X+6Y=10 5X+Y=10
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 10(x-y)=3(x+y)+15 6(x+y)=4(2x-y)+16
解方程组:2/(x+y)+5/(x-y)=18 9/(x+y)-10/(y-x)=66
解方程组:2/(x+y)+5/(x-y)=18 9/(x+y)-10/(y-x)=66
5x-6y=1,2x-6y=10这个方程组怎么解?
解方程组2x+y+x=10 x+2y+z=-6 x+y+2z=8
一次方程组x=y+3 (10y+x)+(10x+y)=99 怎么解
解方程组x+y=15 (x+15%x+y+10%y)=17
解方程组(x+y)(x-2y)=-5 (x-y)(x+2y)=7
解方程组:(0.2x+0.1y)/2- (4x-y)/10=(x-y)/5+ (3x+0.5y)/30 (3x+2y-1
