方程组:4x-2y=4 2x+y=2
方程组x-2y=8,3x-4y=5,x=?,y=?
解方程组X+Y/2=3X-2Y=10+6X+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
已知方程组4x+2y=1,20x+8y,求x,y
已知方程组{3x+4y=10 4x+3y=-2,不解方程组则x+y=
解方程组x^2-y^2=x+y 4x^2-y^2+2x-y=0过程
解方程组:2(x-y)/3-x+y/4=-1 ,6(x+y)-4(2x-y)=16
x+y/2+x-y/3=6,4(x+y)-5(x-y)=2用加减消元法解方程组
3(x+y)+2(x-y)=36 4(x+y)-5(x-y)=2 解方程组
解方程组 {(x+y)/2+(x-y)/3=6 5(x+y)-2(x-y)=4
解方程组 X+Y/2+X-Y/3=6 4[X+Y]-5[X-Y]=2
