算出方程:x/60+x(60-5)/(x+5)+[15-5x/60-5x(60-5)/(x+5)/60=x/60+(15-x)/5的解

算出方程:x/60+x(60-5)/(x+5)+[15-5x/60-5x(60-5)/(x+5)/60=x/60+(15-x)/5的解


x/60+x(60-5)/(x+5)+[15-5x/60-5x(60-5)/(x+5)/]60=x/60+(15-x)/5
x(60-5)/(x+5)+[15-5x/60-5x(60-5)/(x+5)/]60=(15-x)/5
55x/(x+5)+[15-5x/60-5*55/(x+5)/60]=(15-x)/5
55x/(x+5)+[15-5x-275/(x+5)/360]=(15-x)/5
15-x=5* 55x/(x+5)+[15-5x-275/(x+5)/360]
15-x=275/(x+5)+[15-5x-275/(x+5)/360]
x=15-275/(x+5)+[15-5x-275/(x+5)/360]
x=275/(x+5)+[5x-275/(x+5)/360]
x=275/(x+5)+[5x-55/(x+5)]

6-5x=2.5這個方程怎麼算


5x=6-2.5
5x=3.5
x=0.7



一道方程一邊為3/5÷2/5X請問X要先算嗎
這是整道題目3/5÷2/5x=3/4幫我算下


不用先用3/5÷另一邊再除2/5就好了…
