解方程:2/5X+50=(X+50)×5/11
答
2/5X+50=(X+50)×5/11
解:
2/5x+50=5/11x+250/11
5/11x+250/11=2/5x+50
5/11x-2/5x=50-250/11
25/55x-22/55x=550/11-250/11
3/55x=300/11
x=300/11÷3/55
x=300/11*55/3
x=500
答
2/5X+50=(X+50)×5/11
2/5X+50=5/11x+250/11
2/5X-5/11x=250/11-550/11
-3/55x=-300/11
x=-300/11×55/3
x=500
计算过程中要找出最小公分母,把分母化成一样的计算,都是可以消掉的.
