5x+2y=52=3x+2y=36怎么算?
5x+2y=52=3x+2y=36怎么算?
5x+2y=52=3x+2y=36怎么算?
.52=36?
5x+2y=52【1】
3x+2y=36【2】
【1】-【2】得2x=16 x=8
y=4
?题错了吧52=36
要没第二个=
x=8，y=6
可以拆开，5x+2y=52 (1),3x+2y=36 (2)
(1)-(2)得5x+2y-3x-2y=52-36
即x=8，求出y=6
二元一次方程(x+y)/2+(x-y)/3=6,4(x+y)-5(x-y)=2怎么算

x-3y=2 y=x 怎么写
x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2
4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11
3(x+y)-4(x-y)=11,2(x-y)+5(x+y)=27
6(x-y)-2(x+y)=14 3(x-y)+(x+y)=5
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
