2.5x-0.6=1.3x
2.5x-0.6=1.3x
2.5x-0.6=1.3x
2.5x-0.6=1.3x
2.5x-1.3x=0.6
1.2x=0.6
x=0.6÷1.2
x=0.5
2.5x-0.6=1.3x
1.2x=0.6
x=0.5
2.5x-0.6 =1.3x
2.5x-1.3x = 0.6
1.2x=0.6
x=0.6÷1.2
x=0.5
2.5x-0.6=1.3x
3道简单的分式方程,1.3/(1-x^) = 2/(1+2x+x) - 5/1-2x+x^2.5x/(x^+x-6) + (2x-5)/(x^-x-12) = (7x-10)/(x^-6x+8)3.(x+1)/(x+2) + (x+6)/(x+7) = (x+2)/(x+3) + (x+5)/(x+6)
2.5x-2.4=1.3x x等于多少,
0.25x/x-2.5*0.6=0.5
（X+X)+(X-X)+(X*X)+(X/X)=100
x+x-2.5+x-4=85
2.5x+x=10.25 这题解方程怎么算呀求求求!2.5x+x=10.25 75%x-80乘60%=1.286%x-0.6x=52
0.6x(200-X)-4X=106.2 X=?
x-0.5x=1.3
2*x*x+2.5x=13 x=?
X乘X减2.5X=6, 求X!
(8.9-x)/x=0.6
x--0.6x=4.8
x-0.6x=14
0.6x+140 =X
(10000-x)/x=0.6
0.6X+140 =X
x-0.6x=5.6
