11x+42-2x=100-9x-22
方程 0.6(x+4)+0.8=1.2x+0.58 11x+42-2x=100-9x-22
5x+3=x-4,4y+11=22,11x+68-2x=100-9x,0.1x/0.2-(0.27x+0.18)/0.0
(X+X)+(X-X)+(X*X)+(X/X)=100
(4x+2)/x+(4x-22)/(x-5)=(x-6)/(x-4)+(7x+9)/(x+1)
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
11x+42-5x=100-2x-22如何解方程
2x+3x+4x+5x+x+6x+7x=100
x²+4x+9=2x-11
x²+4x+9=2x+11
x-4/1x=8/3 x-0.8x=22 3/2x+2/1x=42
