5y-3=2y+4-6y y=?
1.5y+8y-6y=2y-3
解3y+5/3y-6=1/2+5y-4/2y-4
解方程:(y+4)/5+y+6=(y+8)/2-(y+4)/3
4x-2y-6y*-y-3x+5y* *=2 就是平方
解方程 2y+5/3y-6-y/2=5y-4/2y-4
解方程:2y+5/3y-6 — y/2 = 5y-4/2y-4
(2y-3)(-y+4)=(y-2)(y-5)-3y(y-7/3)解方程
先化简,在求值:6y-(y+2分之y + 2-y分之y)除以y³-4y-2y²+8分之y,其中y=
(-y+5+4y^2)-(-y^2+5y-4),其中y=-2
解方程3y^2-(2y+1)(y-2)=(y-5)(y-1)
解方程:3y^2-(2y+1)(y-1)=(y-5)(y+1)
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
