楼主,
3.2x-1.8x=24
1.4x=24
x约等于1.7
3.2x-1.8x=24
3.2x+1.8x=7.8
解方程:x-60%x=240 x+20%x=24 1-25%x=十六分之三 160%x-x=9 58%x-23%x=24 40%x+70%x-x=1.8
解方程.1.8x+x=24
3.2x+2.2x=10.8 7x-3x=24 x+6.2x=14.4 x-0.84x=21.6 急
(X+X)+(X-X)+(X*X)+(X/X)=100
1.8x-x=2.4x=?
40%x+70%x-x=1.8
x平方=(24-x)(12-x)
X(X+1)(X+2)=24
3X+24=5X-12 3.2X-14.5=3.5-X
8x-5.5x=7.57.2x÷3.6=2 3x+6x-8x=0.7 12x-2x-5x=4.512x-x=0 5x+x=1.8 3.2x+1.8x=64.8x-0.8x=6 6.3-0.3x=9.6 8.6x-8.5x=0.720x-2x=36 9x+6x=4.5 18x-12x=5.42x-1.6x=3.6 18x+3x=7×6 1.2x-0.5x=0.71.3x+2.7x=1 4x-3.2x=6.4 0.8x+3.2x+3x=562.8x-2x=7.2
