解方程：8x-3x=105 x-0.36x=16 13.2x+9x=33.3 2x+1.5x=17.5 2x+1.5x=17.5 2x-x=41.6
解方程：8x-3x=105 x-0.36x=16 13.2x+9x=33.3 2x+1.5x=17.5 2x+1.5x=17.5 2x-x=41.6
帮我解下列方程：13.2x+9x=33.3 8x-3x=105 5.4x+3x=12.8 x-0.36x=16
13.2x+9x=33.3和5.4x+x=12.8和8x一3x=105和x-0.36x=16
13.2x+9x=33.3 8x-3x=105 5.4x+x=12.8 x-0.36x=16
帮我解下列方程：13.2x+9x=33.3 8x-3x=105 5.4x+3x=12.8 x-0.36x=16
要解方程13.2x+9x=33.3 8x-3x=105 5.4x+x=12.8 x-0.36x=16
5.解下列方程：13.2x+9x=33.3 8x-3x=105 5.4x+x=12.8 x-0.36x=16
13.2x＋9x=33.3 5.4x＋x=12.8
13.2x+x=12.8 13.2X+9X=33.3 8X-3X=105 X-0.36=16
解方程 (x-3)÷2=7.5 (x-3)÷2=7.5 13.2x+9x=33.3 8x-3x=105 5.4x+x=12.8 x-0.36x=11
13.2X+9X=33.3 8X-3X=105 5.4X+X=12.8 X-0.313.2X+9X=33.3 8X-3X=105 5.4X+X=12.8 X-0.36X=16 要有过程.
