将左右两边同时乘以5,得到200-X=150,再移项,得到X=50.

括号二百除以x除五等于三十用解方程200÷x÷5=30200÷x=30*5200÷x=150 x=200÷150 x=3分之4

(200-x)÷x=30% (200-x)÷x=0.3 200-x=0.3x 等式的基本性质:等式两边同时加上一个x 200=1.3x x=200÷1.3 x≈153.846后面除不尽

200-x=30*5=150x=200-150=50

(200-x)÷5=30200-x=30*5200-x=150x=50

解:200-x=30*5 200-x=150 x=200-150 x=50

(200-x)÷5=30200-x=150 x=50
