75%X/3=36

x*x=75%x*(x+3)怎么解? 解方程 90-20%x=80 x-25%x=21 x+60%x=3.2 70%x+46=60 （1-75%）x=36 3x+40%x=23.8 3x-1.2x=363x-1.2x=363x-1.2x=363x-1.2x=363x-1.2x=36 75%X/3=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 (56-2X)/(36-2X)=X(56-2X)/(36-2X)=3 x-[2/5x+(x-2/5x-36)*2/3+36]=30 求x (3^x+1)(2^x)-(3^x)(2^x+1)=36,求x的值 4(5x+3)(x+4)=36x平方+8649-1116x求x 若2^x+1 X 3^x+1 = 36^x.求x的值 先化简再求值x^2+x-6/x^4-13x^2+36 (其中x=-3) 36-3X=36-3X x等于多少? 用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+. x^3+12x^2+36x+36=0 (x+x+2.5)*(3/5)=75-(3/7)x 解方程2X-(X+3(X-5)=75 x-1/3x+5=75％x如何解? 解方程：7x-2x+3x=36
