x*x+2*x+1=36,x怎么解,
解方程：x-1/2x=42 x-2/5x=3/8 x+0.8x=36 45-1/2x=5
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
若2^x+1 X 3^x+1 = 36^x.求x的值
(3^x+1)(2^x)-(3^x)(2^x+1)=36,求x的值
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
36/(x-0.3)-36/x=4
36/X-36/（X+1/5X）=1
x-6/x+1/x²+x/x²-36-x-6/x
2^x+1x3^x+1=36^x-2
x-4/1=36 x=?
x-1/4x=1/36
x-1/7x*4=36,
x-1/7x*4=36,
x-1/4x=36
(36-4x)=1 x是什么
