10+5x=73-x,求x.

10+5x=73-x,求x. 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!)+. 已知x=2π+1求 |x-1|+|x-2|+|x-3|+|x-4|+|x-5|+|x-6|+|x-7|+|x-8|+|x-9|+|x-10| 已知x=2π+1.求(X-1)+(X-2)+(X-3)+(X-4)+(X-5)+(X-6)+(X-7)+(X-8)+(X-9)+(X-10) 3^x=2^x,求x.5^(x-1)·10^3x=8^x求x 求x:x(10^x)=100 2x×x=10,求x 78-x=5x 求x 1X?+2X?+3X?+4X?+5X?+6X?+7X?+8X?+9X?+10X?=1980求?是多少 4x+5/2x=10,求x 5^(-x-8)=8^(-10x)求x 5^(-x-8)=8^(-10x)求x x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=? 已知3x*x-x=1,求6x*x*x+7x*x-5x+2000 提取公因式:已知x*x-5x+1=0 求x*x*x-4x*x-4x-1 X/15 + X/12 + X/10 = 1365,求X, 10x-x*x=24 求x
