x/2+y/3=2 2x+3y=28
x/2+y/3=2 2x+3y=28

x/2+y/3=2 2x+3y=28
x/2+y/3=2 可以变成 2x/4+y/3=2;
因为2x+3y=28,所以2x=28-3y
那么,把2x替换一下,2x/4+y/=2就变成（28-3y）/4+y/3=2,
然后化简,得出y=12,x=-2

x/2+y/3=2 --> 3x+2y=12 --> 6x+4y=24
2x+3y=28 --> 6x+9y=84
得到x=-4,y=12

x/2+y/3=2 两边乘6 得到3X+2Y=12和2x+3y=28联立方程组把3X+2Y=12等式两边乘以3 把2x+3y=28 两边乘以2 然后用加减消元法得到X=-4 Y=12

x\2+y\3=2,简化，两边乘以6，变为3x+2y=12即x=4-2/3y....等式1
将等式1代入2x+3y=28。。。等式2,即8-3/4y+3y-28=0,得出y=12，即x=-4

x=-4
y=12
