x-(x+5)/3=37x-(x+5)/3=37x-(x+5)/3=37x-(x+5)/3=37两边同时乘以3得3x-(x+5)=1113x-x-5=1112x-5=1112x=111+52x=116
x - ( x+5)/3 =37
x - ( x+5)/3 =37
x - ( x+5)/3 =37
x - ( x+5)/3 =37 两边同时乘以3得
3x-(x+5)=111
3x-x-5=111
2x-5=111
2x=111+5
2x=116
x=116÷2
x=58
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+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
(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-2x+3x-4x+5x.+99x-100x=25求解
2x+3x+4x+5x+x+6x+7x=100
x(x-2)-2x(x+1)-3x(x-5) 其中x=负½
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
x+(x-3)+(x-5)=37怎样计算
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
3x+5x=?x等于
3x+5x-6x=?
3x+5x=8x.
x^5-2x^3+x=?
8x(x-5)=3x
5X+3【9-X】=37
x - ( x+5)/3 =37
