2(y+3)/5=3y/2-2(y-7)/3如题
2(y+3)/5=3y/2-2(y-7)/3
如题
2(y+3)/5=3y/2-2(y-7)/3如题
12(y+3)=45y-20y+140
12y+36=45y-20y+140
-13y=104
y=-8
因此也非常突出体育法
两边同时乘以三十
12(y+3)=45y-20(y-7)
-13y=104
y=-8
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
5(y-2)-7(y+3)=11(y+4)
(2y-3)(-y+4)=(y-2)(y-5)-3y(y-7/3)解方程
(y^2)^4y-(-2y)^3y^6=
(y-4)(3y+2)-(3y-7)(2y+1),其中y=4/3
2y+5/3y-6-y/2=5y-4/2y-4
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)
解方程:3y²-(2y+1)(y-2)=(y-5)(y+1)
{2x+y/3-2y=0 2(2x+y)-5=7y
3-5-2y/5=y-4-7y/10+y+2/2
10y+2(7y-2)=5(4y+3)+3y怎么算
10y-2(7y-2)=5(4y+5)-3y
4(2y+5)-3y=7(y-5)+4(2y+1)
y-7-8y=2y-3-5y 咋写?
