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!
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
(X+X)+(X-X)+(X*X)+(X/X)=1002X+0+X*X+1=1002X+X*X=99X(X+2)=99X=9再问:请问X(X+2)=99解为什么就等于9了呢没看懂再答:换成算术法你就明
我来再答: 再答:快再问:三扣再答:呵呵
0.64x=16x=16÷0.64x=25
8x-3x=1055x=105x=21x-0.36x=160.64x=16x=2513.2x+9x=33.322.2x=33.3x=1.52x+1.5x=17.53.5x=17.5x=52x-x=41
①1.4x-0.4x=19.8(1.4-0.4)x=19.8x=19.8②x-0.36x=16(1-0.36)x=160.64x=16x=16÷0.64=25

再答: 再答: 再答: 再问:错了再答:哪题?再答:哪题错了?
第二个是再答:5x=105
x+0.36x=161.36x=16x=16/1.36x=200/17x=11.76
0.2x=16x=80
x-0.36x=160.64x=16x=16/0.64=25
