(7/6X-360)÷(X-360)=2/3
(7/6X-360)÷(X-360)=2/3
(7/6X-360)÷(X-360)=2/3
(7/6X-360)÷(X-360)=2/3
方程两边同时乘以(x-360)得:
7/6X-360=2/3(X-360)
7/6X-360=2/3X-360×2/3
移项:7/6X-2/3X=-240+360
7/6X-4/6X=120
1/2X=120
X=240
★经检验:240是原方程的根.
答:原方程的解为240
(7/6X-360)÷(X-360)=2/3
7/6X-360=2/3X-240
1/2X=120
X=240
(7/6X-360)*3=(X-360)*2
7/2X-360*3=2X-360*2
(7/2-2)X=360*3-360*2
3/2X=360
X=360*2/3
X=240
(7/6X-360)÷(X-360)=2/3
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,
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
6X-(360X-0.5X)=2×(360X-0.5X)
6X-(360X-0.5X)=2×(360X-0.5X)怎么算?
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
