0.7分之x减0.03分之0.17减0.2x=1,(0.17减0.2x是分子,0.03是分母).0.7分之x减0.03分之0.17减0.2x=1,(0.17减0.2x是分子,0.03是分母).0.7分

0.7分之x减0.03分之0.17减0.2x=1,(0.17减0.2x是分子,0.03是分母).
0.7分之x减0.03分之0.17减0.2x=1,(0.17减0.2x是分子,0.03是分母).

0.7分之x减0.03分之0.17减0.2x=1,(0.17减0.2x是分子,0.03是分母).
方程可变为:10x/7-(17-20x)/3=1
去分母,得:30x-119+140x=21
移项,得:30x+140x=21+119
合并同类项,得:170x=140
方程两边同时除以170,得:x=14分之17
