解方程组(3x+4y-3)(3x+4y+3)=0&3x+2y=5
解方程组(3x+4y-3)(3x+4y+3)=0&3x+2y=5
解方程组(3x+4y-3)(3x+4y+3)=0&3x+2y=5
把第二个方程带入第一个方程啊:就有(2y+2)(2y+8)=0立即可以解出y=-1或者-4;将y=-1带入第二个方程3x+2y=5可以解出x=7/3;同理带入y=-4就有x=13/3;所以方程组有两组解啊:x=7/3&y=-1;x=13/3&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3x+5(x+y)=2 3y-2(x+y)=4
解方程组:{4x+5(x-y)=30,4y-3(x-y)=6
解方程组,x+y/2=3x-2y=10+6x+y/4,
方程组4=x+y,8=3x-y求x,y的解
解方程组:2(x +y)-3(x-y)=3;4(x+ y)+ 3(x-y)=15
解方程组24/(x+y) +24/(x-y) = 7/3 ,8/(x+y) +18/(x-y) = 4/3
解方程组⑴(x+y)/2-(x-y)/3=6,⑵3(x+y)=4(x-y)
解方程组 x-y/3-x+y/4=2 x-y/6-x+y/8=3
解方程组;x+y/2=x-y/3=6 4(x+y)-3(x-y)=-20
解方程组4(x+y)-3(x-y)=14;(x+y)/2+(x+y)/3=6
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2(x-y)/3-x+y/4=-1 6(x-y)-4(2x-y)=16
解方程组3(x+y)-4(x-y)=4和(x+y)/2+(x-y)/6=1kkkkkkkk
3(x+y)—4(x-y)=4,(x+y/2)+(x-y/6)=1.解方程组
解方程组3(x+y)-4(x-y)=4,x+y除以2+x-y除以6=1
解方程组:2(x-y)/3-x+y/4=-1 ,6(x+y)-4(2x-y)=16
