①:50*(x+0.2)=60*(x-1) ②:50*(x-2+8)=(50+10)*(x-2-5)
①:50*(x+0.2)=60*(x-1) ②:50*(x-2+8)=(50+10)*(x-2-5)
①:50*(x+0.2)=60*(x-1) ②:50*(x-2+8)=(50+10)*(x-2-5)
① 50(x+0.2)=60(x-1),50x+10=60x-60,10x=70,x=7.②50(x-2+8)=(50+10)(x-2-7),50(x+6)=60(x-9),50x+300=60x-540,10x=840,x=84.
50x(x-1)+60x(x-4)=5100
①:50*(x+0.2)=60*(x-1) ②:50*(x-2+8)=(50+10)*(x-2-5)
x除55%=100 60%x=30 x+50%x=4.5 (1-25%)x=72 4x+40%x=176 解方程
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
解方程 40%x=12 (1+60%)x=24 (1-37.5%)x=10 2x+50%x=20 40%x+30%x=140 35%x-15%x=72
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
45X(x+1)=60X 怎么解
45x+10 =50X(x-1)
x(x-1)(x+1)=60
x/(120-x)=x/60
:① 60%÷120%-3X=20% ② 1÷(X+三分之二)=80% @ X+75%X=15 @75%X-三分之一X=10
x/60+1=x/50-1
已知x除以(x*x-x+1)=7,求x*x除以(x*x*x*x+x*x+1)的值
(解方程)要有过程的喔!①x-1/4x=3/8②(1/5+1/2)x=3/20③0.3(x-9)=12.75④x+2/7x=3/4⑤(3/4+2/5)x=23/24⑥3x-27/4=33/4⑦7/4x-1/2x=25/4⑧2x-2/3=4/5⑨x+2/5x=2110、 2/3x-13/50=1/5x11、 4/5x-2/5x=1/212、 0.2x+0.8=6.413、 (1-3/8)x=5/31
45X=60(X-1)
(x-1)+(x+2)+0.2x+2x=46
12x(x+x)=60 X=?
