132/X=121/(X-35),
132/X=121/(X-35),
132/X=121/(X-35),
132/X=121/(X-35)
132(x-35)=121x
12(x-35)=11x
12x-420=11x
x=420
十字相乘
132/X=121/(X-35)
132(X-35)=121X
132X-132*35=121X
132X-121X=132*35
11X=132*35
X=(132*35)/11
X=420
当X=420时,X-35=385不等于0,则X=420
132/X=121/(X-35),
(x+x)+(x-x)+(x/x)=11.2
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
7x²-4x-3=0 -x²-x+12=0 x²-6x+9=0 (3x-2)²=(2x-3)² x²-2x-4=0 x²-3=4x 6x²-31x+35=0 (2x-3)²-121=0 2x²-23x+65=0
x+x÷5+(x+35)=112
(5-X)X(7-X)=35 和(5+X)X(7+X)=35
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
5x+(15-x)=35
(X-35)%=39 求X?
x(x-1)=132 求x
(X+X)+(X-X)+(X*X)+(X/X)=100
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
x+35=(x+3x)*30%
35道.符号^代表平方.读起来就是(X的平方).1,x^-x-202,x^-9x+203,x^-9x-204,x^+9x+205,x^-18x+326,x^+14x-317,x^+18x+328,x^+14x-329,x^+19x+4810,x^+47x-4811,x^+13x-4812,x^+2x-4813,x^+26x+4814,x^-22x-4815,x^+17x+7216,x^+21x-10017,x^-x-7218,x
x/(120-x)=x/60
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:10×(x-5)+x+[10x+(x-5)]=121
解方程:10×(x-5)+x+[10x+(x-5)]÷10=121
