36/X - 36/(X+0.6)=2 怎样解算出来 请尽快

10x -6.2x-2x=36 x=? x+2x×10=10x+2x+36 解方程：（x+2)(x+2)-x*x=36 x*x+2*x+1=36,x怎么解, (180x-36*x)/(x+2x)*2x=(180x-36*x)/(x+2x)*x+36x 这个怎么解啊···· [(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 解方程:x/4=30% 36/x=3/4 10/x=2.5/0.8 x/4=1.2/5 X/1.2=1.5/0.6 x/0.4=1.5/6 x/7=0.6/3.5 x/10=0.1/25-3x=8x+1 2(x-2)+2=x+1 3-x=2-5(x-1) 3x=5(32-x) 7(4-x)=9(x-4) 7x-8=2x+27 5x-18=3-2x (7x-4)+3(x-2)=2x+6 2(3x-4)+(4-x)=4x我是六年级的学生,我希望 (56-2X)/(36-2X)=X(56-2X)/(36-2X)=3 x-[2/5x+(x-2/5x-36)*2/3+36]=30 求x X^2-2X-4=0 X（X-7）=5X-36 (10 x 2x + 2x)- (10x + 2x) =36 (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+12x^2+36x+36=0 2x+1.5x=7/36,x=几 72/x-36/x^2-11=(6-x)^2
