解方程(3x+2y)/4=(2x+3y)/5=(x-1)/6
解方程:3x+2y/4=2x+y/5=x-y+1/6要详细过程
解方程x+y+(x+y/2)=15 3x+5y+4(x+y/2)=62
(x+y)-(x+y)平方 因式分解 解方程 2x²=3x (3x-1)² - 4=0 5x-15x
解方程(3x+2y)/4=(2x+3y)/5=(x-1)/6
用代入法解方程2(x-y)/3-(x+y)/4=-1① 6(x+y)-4(2x-y)=16②
求方程x+2y-3x=4,3x-2y+x=6,3x+2y-5x=8的解
解方程:(1)4x+7y=10 (2)x+y-z=0 6x-11y+28=0 x+2y-z=3 2x-3y+2z=5
解方程:x-x-1/2=2-x+2/3 y+6=y+2/2-y-5/3
解方程(3x+2y)/4=x+1/3y=3(x-2)+y
解方程一;{x+y-z=6,x-3y+2z=1,3x+2y-z=-7.②{3x+4z=7,2x+3y+z=9,5x-9y
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
