36/(x-0.3)-36/x=436/(x-0.3)-36/x=436/(x-0.3)-36/x=4先去分母,两边都乘以4x(x-0.3)
36/(x-0.3)-36/x=4
36/(x-0.3)-36/x=4
36/(x-0.3)-36/x=4
先去分母,两边都乘以4x(x-0.3)
36/(x-0.3)-36/x=4
[(x+6)/(x-6)][(x-4)/(x+4)]^2+[(x-6)/(x+6)][(x+9)/(x-9)]^2=2(x^2+36)/(x^2-36)
解方程 式子 6-2x+3x=3x-4x+3x+18 6-x+3x=2x-5x+1 2x-1=5x-36-2x+3x=3x-4x+3x+18 6-x+3x=2x-5x+12x-1=5x-3
8x-5.5x=7.57.2x÷3.6=2 3x+6x-8x=0.7 12x-2x-5x=4.512x-x=0 5x+x=1.8 3.2x+1.8x=64.8x-0.8x=6 6.3-0.3x=9.6 8.6x-8.5x=0.720x-2x=36 9x+6x=4.5 18x-12x=5.42x-1.6x=3.6 18x+3x=7×6 1.2x-0.5x=0.71.3x+2.7x=1 4x-3.2x=6.4 0.8x+3.2x+3x=562.8x-2x=7.2
4(5x+3)(x+4)=36x平方+8649-1116x求x
X^2-2X-4=0 X(X-7)=5X-36
先化简再求值x^2+x-6/x^4-13x^2+36 (其中x=-3)
0.3x+7x-0.25x=21.58.7×(36-x)=04(不知道是x还是× 都解了吧)x或者×(x+0.2)=1.27(x+6)-3x=4x(2x+5)3(x+2)=4(x+1)18-4x=2x-63.8x+1.2x=256x+1.5x=15呼呼.累死我了 着急
X平方+5X=36,X等于4,
36+x=4x(6+x)怎样计算?
x*9+x*36+4x*12
x-4/1=36 x=?
5x十4x=36
36+4x=6x-34
4x+2*(12-x)=36
x-1/7x*4=36,
4x²-36x=27
6X+36-4x=44
