2/3x+36=x

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 (X+1)X(X+2)X(X+3)=504 一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X (56-2X)/(36-2X)=X(56-2X)/(36-2X)=3 x-[2/5x+(x-2/5x-36)*2/3+36]=30 求x x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少? (3^x+1)(2^x)-(3^x)(2^x+1)=36,求x的值 先化简再求值x^2+x-6/x^4-13x^2+36 (其中x=-3) 若2^x+1 X 3^x+1 = 36^x.求x的值 (x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3) 解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6) x(x-2)-2x(x+1)-3x(x-5) 其中x=负½ x-2x+3x-4x+5x.+99x-100x=25求解 x+3x+x-2+x+x+50%x=188 求x 2x+3x+4x+5x+x+6x+7x=100 x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x 请问这道题咋做 ：（x）X (x+1) X (x+2) X (x+3) =360 x^3+12x^2+36x+36=0
