25x-4x=32-0.5
4x+32=25x+0.5
32+4x=25x+0.5
4X+0.5X=13.5X
2x(7-3x)+5x(2x+1)=x(4x-3)+32
x-2x+3x-4x+...+99x-100x=25
先化简再求值先化简再求值:(x-x/x+1)(x+1/x^2+4x+4)(x^2-4/x^2-2x),其中x=-0.5
x/x-4 - 32/x的平方+16=1 x+1/x + 5X/x+1=6
解方程:(2x+5)(4x*x-10x+25)=8x(x*x+1)
1. x+0.5x=6 4x+16=40 x/5=32% x-4/9x=10/21 x-1/8x=5/8 7x÷2=2.
解方程5X+35=140-2X 9X-27=70+4X 12+7X=2X+32 250/X+25=75 23X-72X+
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
