3.5x÷7=1 解方程 3.5x÷7=1 3.5×=7 ×=7÷3.5 ×=2

5.2-x-5.2=1.7-5.2 -x=-3.5 x=3.5

3/7÷x×1/3=5/14 3/7÷x=15/14 x=3/7÷15/14 x=3/7×14/15 x=2/5

27-1.7X=13.4 1.7X=27-13.4 1.7X=13.6 X=13.6÷1.7 X=8 不懂可追问,有帮助请采纳,谢谢!

因题干条件不完整,缺题干,不能正常作答

x/4=30% x=4*30%=120% 36/x=3/4 3x=36*4 x=36*4/3=48 10/x=2.5/0.8 2.5x=10*0.8 x=10*0.8/2.5=3.2 x/4=1.2/5 5x=4*1.2=4.8 x=4.8/5=0.816 X/1.2=1.5/0.6 0.6x=1.2*1.5 x=1.2*1.5/0.6=3.0 x/0.4=1.5/6 6x=0.4*1.5 x=0.4*1.5/6=0.1 x/7=0.6/3.5 x=...

X十1.7=4÷0.4 X十1.7=10 ×=10-1.7 ×=8.3

2.4(1.7十x)=21.6 解:(1.7十x)=21.6÷2.4 1.7+x=9 x=9-1.7 x=7.3

1.7(2x-1)-3(4x-1)=4(3x+2)-1 2.(5y+1)+ (1-y)= (9y+1)+ (1-3y) 3.[ (- 2)-4 ]=x+2 4.20%+(1-20%)(320-x)=320×40% 5.2(x-2)+2=x+1 6.2(x-2)-3(4x-1)=9(1-x) 7.11x+64-2x=100-9x 8.15-(8-5x)=7x+(4-3x) 9.3(x-7)-2[9-4(2-x)]=22 10.3/2[2/3(1/4x-...
