解答
前提必须是a不等于0
两边都乘以30/a
得出：2+2x+3x=30
x=5.6
推荐
- （（10-x）a+bx）/10=（（15-x）b-ax）/15
- 请问若x`2+ax-15=(x+3)(x+b),则a=?,b=?
- 若x^+ax-15=（x+3）（x+b）,则a=______,b=________
- 已知x＝2y＝5和x＝1y＝10是方程ax+by=15的解，则a=_，b_．
- 已知｛x=2,和｛x=1,是方程ax+by=15的两个解,求a,b的值.y=5 y=10
- to his surprise ,this time there were six .
- 用形容词的适当形式填空 In this country it's very ------(cold)in November,and it's much
- he stepped into the room quietly without being noticed.后面的without being noticed是什么意思?
