1.3÷X等于0.52怎么解方程

1.3÷x=0.52 x=1.3/0.52 =2.5

1.3÷x=0.52 x=1.3/0.52 x=2.5

(1)1.3÷x=0.52, 1.3÷x×x=0.52×x, 1.3=0.52x,0.52x=1.3,0.52x÷0.52=1.3÷0.52, x=2.5;(2)10.2-5x=2.2, 10.2-5x+5x=2.2+5x, 10.2=2.2+5x,2.2+5x=10.2, 2.2+5x-2.2=10.2-2.2, 5x=8, 5x÷5=8÷5, x= 8 5 ;(3)3×1.5+6x=33,4.5+6x=...

x=1.3+0.52,x=1.82

解方程:(1)x÷0.26=0.52 x÷0.26×0.26=0.52×0.26, x=0.1352;(2)9x-2x=21.7, 7x=21.7, 7x÷7=21.7÷7, x=3.1;(3)3.18×2-2x=4.26, 6.36-2x=4.26, 2x=6.36-4.26, 2x÷2=2.1÷2, x=1.05; (4)0.25x+3.75=12.0.25x+3.75-3.75=12-3.75...

解方程:(1)x÷0.26=0.52 x÷0.26×0.26=0.52×0.26, x=0.1352;(2)9x-2x=21.7, 7x=21.7, 7x÷7=21.7÷7, x=3.1;(3)3.18×2-2x=4.26, 6.36-2x=4.26, 2x=6.36-4.26, 2x÷2=2.1÷2, x=1.05; (4)0.25x+3.75=12.0.25x+3.75-3.75=12-3.75,...

X-35%X=0.52 x-0.35x=0.52 0.65x=0.52 x=52/65 x=4/5

x-0.52x=3.2×0.15解方程 解:0.48x=0.48 x=1

x-0.52x=3.2乘0.15 0.48x=0.48 x=1

0.48x=0.48 x=1
