(X-80)*0.67/4200=(X-160)*0.67/4000,等号两边同时除以0.67,再同时乘以200,得:(X-80)/21=(X-160)/20,即:(X-80)×20=(X-160)×21,即20X-80×20=21X-21×160,即X=21×160-20×80=1760.
3x*x=1600+x*x-80x
(X+X)+(X-X)+(X*X)+(X/X)=100
x-25=80%x,x=?
x(120+x)*80%=x-76
60%X + 80%X - 12 = X
125x(80+8)=( )x( )+( )x( )
80%x+30-x=10%x
5*4x+x*x=80
536-120%x-x=x-80
x-0.2x=80 求x
80X-90X=6x+80X 解是几
80+x=(56-x)*3 x=x
x+x=x+80,x等于多少?
x*x*x*x*x=80000?
x+60%x=80
