5.4x+x=12.86.4x=12.8x=12.8/6.4x=2
X-0.36*X=160.64X=16X=16/0.64X=255.4X+X=12.86.4X=12.8X=12.8/6.4X=2
雨爱and可爱,您好:x-0.36x=161-0.36*1=161-0.36x=160.64x=16x=25这是这样做的,请您采纳.谢谢!
6.4x=12.6再答:12.8再答:x=12.8/6.4再答:x =2再答:00.64X=16再答:X=16/0.64再答:X=25再答:采纳吧再问:第二题看不懂再问:照过来再答:减一下
5.4X+X=12.86.4x=12.8x=2X-0.36X=160.64x=16x=25
5.4x+x=12.86.4x=12.8x=12.8/6.4x=2
0.64x=32x=32/0.64
4.5+x=12.84.5+x-4.5=12.8-4.5=8.3
解5.4x+x=12.8即6.4x=12.8两边除以6.4即x=12.8÷6.4=2即x=2
13.2x+9x=33.322.2x=33.3x=1.58x-3x=1055x=105x=215.4x+x=12.86.4x=12.8x=2x-0.36x=160.64x=16x=25
13.2x+9x=33.38x-3x=105(13.2+9)x=33.3(8-3)x=10522.2x=33.35x=10522.2x÷22.2=33.3÷22.25x÷5=105÷5x=1.5x=2
错了是不是x/0.36=16?x=16×0.36x=5.76
我来再答: 再答:快再问:三扣再答:呵呵
13x-5x=12.88x=12.8x=1.6
0.64x=16x=16÷0.64x=25
13.2x+9x=33.322.2x=33.3x=1.58x-3x=1055x=105x=215.4x+3x=12.88.4x=12.8x=1.5238x-0.36x=160.64x=16x=25再问
9x-5x=21.64x=21.6x=5.4再答:2.4x+4x=12.86.4x=12.8x=2再答:x-0.36=32x=32+0.39x=32.36
