0.5x-6=0.75x
0.5x-6=0.75x

0.5x-6=0.75x
0.5x-6=0.75x
0.5x-0.75x=6
-0.25x=6
∴x=-24

x=-24

-24

0.5x-6=0.75x
0.5x-0.75x=6
-0.25x=6
x=-24

0.5x-6=0.75x
0.5x-0.75x=6
-0.25x=6
x=6/(-0.25)
x=-24

-24

是求解X吗
将0.5X移项得：-6=0.25X
等式两边同时除以0.25得：
X=-24

-6=0.75x-0.5x
-6=0.25x
x=-24

0.75x-0.5x=-6
0.25x=-6
x=-24

0.5x-6=0.75x (x+2)(x-1)+(x+3)(x+1)=x·x-1 求x (5x-4)(2x+5)(3x-6)(2x-4)=(2x-4)(2x+5)·0.5 求x 6X-（360X-0.5X）=2×（360X-0.5X） 6X-（360X-0.5X）=2×（360X-0.5X）怎么算? x/x-2+x-9/x-7=x+1/x-1+x-8/x-6, x/x-2+x-9/x-7=x+1/x-1+x-8/x-6, 6x+15=87 8X-0.5x=15 x+0.6x=11.2 0.5x=4/5(6+x)x=? 0.5x=0.75(1000-x) 0.75x+0.5x=2.25 x=0.5,6x+x^2怎么算 0.75x+6=2x-15 x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少? 8(x-0.5)=6(x+0.5) 8(x-0.5)=6(x+0.5) x+0.5x=6 怎么算? 3x+6x×0.5=18 int x=6; x += x -= x * x; printf(x = %d ,x);
